Mnemonics are easy-to-remember lines or phrases one can use to memorize things that are difficult to learn. In this article, you will find Hindi mnemonics – one each for one group – to learn the Periodic Table The Periodic Table provides the names, atomic numbers, symbols and atomic weights of known elements. It serves as a great tool for solving chemistry problems.
A periodic table is divided into groups (columns), where elements with each group behave similarly while bonding with other elements; and periods (rows), where elements in one period have same number of electron shells.
Here are some fun, interesting and naughty mnemonics in Hindi used by the backbenchers to memorize elements along each group or period:
KEY TO READI NG TH ESE M NEM ONICS OR H I NDI SENTENCES: • These sentences contain letters denoting symbols of elements in the same order as they occur in a group or period. • The symbols have been highlighted as bold letters in the sentence. However at the places where the complete symbol could not be included in the sentence, the first letters have been strung together and the second letter is shown in brackets. While reading the sentence you don’t have to read the letters in bracket. Just keep them in mind. • At some places, phonetics have been used to denote a symbols such as ‘c’ could be replaced by ‘k’,’g’ with ‘j’, ‘I’ with ‘ea’ and ‘o’ with ‘u’, to make the sentence easier to remember.
S-Block Elements Consisting of the first two groups, S -block elements have quite similar physical and chemical properties. The valence electrons o f the elements in this block occupy s-orbitals.
Group 1 is kno wn as alkali metals. It includes Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Ru), Caesium (Cs), and Francium (Fr).
Mnemonic for Group 1: LiNa K i Ru by Cse Friendship hai.
Group 2 is known as alkaline earth metals. It includes Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Br), and Radium (Ra).
Mnemonic for Group 2: Beta Mange Car Scooter Baap rone se Raazi
P-Block Elements Consisting of last six groups of the periodic table (Groups 13 to 18), P -block elements have their valence electrons occupying porbitals. This block consists of non-metals, semi-metals and poor metals.
Group 13 is known as Boron group o r the group of Icosagens or Triels. It includes Boron (B), Aluminium (Al), Gallium (Ga), Indium (In), and Thallium (Tl).
Mnemonic for Group 13: B A G I T.

Mnemonic for Group 17: Fir Call kar Bahaar AayI Aunty.
Group 18 is known as the group of No ble gases, excluding Helium. Normally, they are all odorless and colorless gases with very low chemical reactivity. The group includes Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and the radioactive Radon (Rn).
Mnemonic for Group 18: He Never Arrived; K ara Xero R un pe out.
D-Block Elements D-Block elements consist of element groups 3 to 12 that correspond to the filling of the d -orbital subshell of the second outermost shell. Groups 3 to 11 are also known as transitional metals. Group 12 elements, which have its d subshell completely filled, are also known as post-transition elements.
D-block elements and F-block elements show considerable similarities across the periods too.
We can memorize these elements across the periods:
Period 4 elements are quite stable and many of them are very co mmon in earth‘s crust or core or both. D-block elements it includes are Scandium (Sc), Titanium (Ti), Vanadium (V), Chromium (Cr), Manganese (Mn), Iron (Fe), Cobalt (Co), Nickel (Ni), Copper (Cu) and Zinc (Zn).

it includes are Actinium (Ac), Rutherfordium (Rf), Dubnium (Db), Seaborgium (Sg), Bohrium (Bh), Hassium (Hs), Meitnerium (Mt), and Darmstadtium (Ds).
Mnemonic for Period 7: Ak (c)ele R (f) D(b) S(g)harma ki B(h)ook mein H(s)ain Maths ke Difficult sawaal. Read as: Akele R D Sharma ki Book mein Hain Maths ke Difficult sawaal.
F-Block Elements F-block elements have their valence electrons in f-orbitals. They are also known as inner transition elements. They can be divided into Lanthanides (also known as rare earth elements) and Actinides that are highly reactive to halogens and chalcogens like lanthanides but they react more easily.
Lanthanides include Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Promethium (Pm), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb) and Lutetium (Lu). We can learn all these in three parts:

1.
Follow NCERT Syllabus
All medical aspirants should treat NCERT syllabus as their ‘Bible’. Thoroughly read all the study material, understand it well, learn it up wherever you have to and re vise it all again.Do not ignore the diagrams. Many AIPMT questions are diagram-based and they can significantly affect your scores. You can refer to AskIITians study material to cover these topics in -depth.
2.
Important Topics
Remember, ‘all’ topics are important. It is necessary to study all of them. But the analysis of past years’ AIPMT and NEET UG question papers show that relatively more questions have been asked from Human Physiology, Biomolecules and Biotechnlogy.Animalia can be quite exhaustive. Hence, it should be prepared very carefully. In Non-Chordates, one should emphasize on the characteristics of different beings up to ‘Phylum’ level. In Chordates, one should know characteristics of beings up to ‘Classes’ level. The examples given in NCERT books are important too. Learn them all along with their common names.
3.
Preparation Strategy
Candidates should divide all the topics in two groups – ‘To be Understood’ and ‘Information based Topics’.The latter will include topics like Animalia and Morphology of Animals and will have to be learnt by heart. Such topics are best covered in the last phase of preparation for better retention. Start with topics you need to understand first. Once you complete a topic, solve questions related to it on regular basis. You will find many questions in Daily Practice Papers (DPPs). They will help you retain a topic better. In case, you are not able to solve a particular question, immediately consult your teacher and get your doubt cleared.
4.
Solve Previous Years’ Question Papers
When you solve AIPMT question papers of previous years or NEET UG paper of last year, you get a general idea about the difficulty level of the exam, exam pattern, types of questions asked in the exam and what to expect on the examination day.Besides, practice can only make you perfect.
5.
Read question carefully
It is very important to read a question carefully. You should not assume anything. Read it until you are sure of what one actually wants. If you read only half-a-question, you may misunderstand what is actually required.Make sure whether you have to choose the correct statement or the incorrect statement. It is a most common mistake that students make. Mark an answer only when you are sure you have understood the question.

There is a sufficient amount of research which shows that taking a break is good for everyone. It stimulates creativity and productivity and the absence of a break can lead to stress and exhaustion.
No doubt that the great Archimedes, who was given the task of measuring the volume of an oddly-shaped crown, had his ―a-ha moment‖ when stepping into a bath. Or even Kekule was said to have thought of the structure of benzene while riding on a bus? Value of summer vacations
Summer vacations are indeed the most awaited vacations for any kid! These vacations can end up being really boring if there‘s no outing planned out or a schedule marked out for kids. While kids are p acked up with their homework, tuitions and time for games, there might be times when kids feel like doing something extra which would h elp them pass their time. In this interest, we have listed a few activities for young, budding minds which can be extremely fun and can be picked up as hobbies as well. Go through the list below and see what interests you the most!
1. Begin collecting- Well, you may have heard of people maintaining collections of coins, stamps, books, records etc. You can
also come up with innovative ideas. Just ensure that these ideas are not too expensive and involve collecting something that really interests you. This could be collection of old pictures, posters, differently colored stones etc.
2. Learn something creative- This could be learning any art form th at you always wanted to do. The list could range from- a
particular type of dance form, painting, vocal music, martial arts, instrumental music, pottery, cooking etc. It‘s really good if you pick up anything like this and learn it in the early days of your childhood as an art form helps you become a better person and brings out the creative element hidden in every kid.
3. Swim like a fish! Kids who know ho w to swim, definitely know the fun I am talking about. For those of you who don‘t, this
activity is one of the most refreshing and fun activities. You can even do water sports once you learn how to swim. Moreover, a cool and rejuvenating swim in the summers can make you feel really cool and provide you some respite from the heat!
4. Start a library - If reading is your hobby then you can start a book club or a library by yourself or with your friends. Lay your
hands on the books that you can find and create a fun collection of books. With this you can start a book club wherein you and your friends read the same book each week and discuss about it. Also, you can invite others to borrow books for you and charge them a minimal fee too. This way you will be close to your books too, but in a fun way!
5. Nurture plants- Did you feel this was one of those activities done by the elderlies? Well, no! I t‘s one of those activities that
gives one a really good feeling and can be done by all age groups. As kids, you can ask an elder or a friend to get you a seed or a sapling and plant it near your house. The entire respon sibility of the plant is on you till the time it grows.
6. Do some social work - Social service does not necessarily mean charity. You can help the community in ways more than one.
Just help a neighbour who may not be able to complete tasks alone or participate in cleanliness drives or education programmes for kids who can‘t afford school. In short, make the world a better place to live in! Hope some of these activities interest you and you find a good way to enrich the time you spend during your vacations!
Have fun!

People give very high importance to educationin India. Whenever parents of two kids meet, irrespective of the age or standard in which the kid is studying, the parents‘ discourse automatically turn towards their studies! That sounds funny, but it is definitely a good thing as education is the pillar to a better tomorrow. Though parents in our country always try to give best to their child in terms of education, but there is always confusion for parents to choose between CBSE (Central Board of Secondary Education) and ICSE (Indian Certificate of Secondary Education) boards. Very few know what are the d ifference between them and their education patterns, and the advantages and disadvantages of their education patterns. Thus we have trief to gather some details about both education patterns to make it easier for you to select right pattern for your child. Merits of CBSE Board1.
CBSE is more popular in India as compared to ICSE.
CBSE being older, more schools follows CBSE pattern syllabus and education methods. That is why CBSE pattern is more popular here. This will help you to find a school easily for your kid in case you are switching to new city in India. Also, if you want to travel abroad then you will find more CBSE pattern Indian schools outside India than ICSE. CBSE is recognized by Indian government while ICSE is not. The popularity of ICSE is growing day by day tho ugh. Thus CBSE is recommended for parents who have to move in different cities in India as part of their job profiles. CBSE has more schools in India and their children will not face any issue while switching schools.
2.
CBSE has less syllabus volume as compared to ICSE
Some students may find ICSE syllabus vast as ICSE h ave more syllabus and subjects. A sixth grade ICSE student will face 12-13 subject examinations, while CBSE student will face only 5 -6 subject examinations.
3.
CBSE board helps more in engineering and medical field
CBSE is more focused on math and science subjects. This helps students for engineering and medical entrance exams better. Prior CBSE experience will be always helpful for students doing their medical and engineering preparations.
4.
CBSE has more Scholarships and talent search exams
ICSE being newer has got less numbers of scholarship exams as of date. CBSE has lot of talent search examinations for a stude nt. All major competitive examination in India are based on the CBSE syllabus. For ecample, JEE (Joint Entrance Examination) main and JEE-Advanced, AIEEE (All India Engineering Entrance Examination), AIPMT (All India Pre Medical Test) etc. Merits of ICSE Board
1.
ICSE has more balanced Syllabus for child’s overall growth
CBSE syllabus is easier as compared to ICSE syllabus. CBSE syllabus is focussed more on Science and Maths. While on the other hand, the syllabus followed by the ICSE board is more comprehensive and complete that gives all fields equal importance. For ecample, maths, science, languages, art, home sciences, agriculture, cookery, fashion designing etc are all given importance. By choosing ICSE you are giving opportunity for your child to work on his overall growth.
2.
ICSE prefers to give more practical knowledge and teach better analytical skills
Compared to CBSE syllabus, ICSE is more inclined towards giving practical knowledge to the students. Their is an equal emphasis on providing theoretical a well as practical learning. This gives students effective understanding of subject, and they learn better analytical skills.
3.
In ICSE, student has more Subjects Flexibility
ICSE is having much advantage over CBSE in this. Students in ICSE can choose different subjects. Students ca also select vocational courses as per their interest. Whereas in CBSE, students have to follow pure academic subjects.
4.
ICSE prefers more student Assessments
In ICSE, the internal assessments are very crucial. More practical tests are conducted with all the subjects and scores. Thus ICSE gives more preference to lab work and hence it is more practicality oriented.
5.
ICSE board helps more on management carriers
The way the ICSE syllabus, its portions, its subjects and teaching methodology is designed, it is any d ay more helpful for students who wants to pursue their carriers in management streams, as compared to the CBSE board stud ents.
6.
ICSE certificate is recognized around the world
Certificate given by ICSE to the students, is recognized more around the world, as compared to CBSE board. Overall syllabu s of ICSE gives a slight upper hand in english to its students. Therefore it helpe them clear the scholarship exams better, especially ones that are based on English. ICSE is recommended for p arents who have to move in different countries as part of their job and wish to enroll their children in international schools. ICSE is more compatible to the world as compared to CBSE syllabus. IC SE child will face less difficulty while changing his school internationally.
Common factors between CBSE and ICSE-
CBSE and ICSE are both recognized by colleges in India.
The main subjects taught in ICSE and CBSE are almost same.
Quality of education provided by both boards is excellent.
CBSE & ICSE both education patterns follows way of learning through experience. But, following methods defined in respective patterns always depends on the schools and teachers. Thus this can vary from school to school.
So, what should the parents do?
Both the boards, CBSE and ICSE, have their own merits and d emerits. Parents have to choose the board for their children based up on what future they aspire for their children, and majorly on what future career interests their children. Parents always have concern with quality of education. Thus, for this, they should identify the best schools for their children, because whatever the board they would choose, ultimately the schools would play a larger role in imparting the right kind of education to their children.
Sarthak, 12th Class topper with 99.6% marks, shares his success secrets with all! askIITians

His father called it ‗Skating on thin ice‘. But he chose to focus on the task in hand, instead of worrying about the future. The rest was history. Sarthak Aggarwal, the student of Delhi Public School in Vasant Ku nj, emerged as the topper of this year‘s CBSE class XII Board exams , with 99.6 % marks in the Science stream! Sarthak, in an interview said that Class XII board exam is an important juncture in every student‘s life, as it marks a transition from school to college. He too gave a lot of significance to these exams as he wanted to pursue a graduate degree in economics and admission to the best college would have depended entirely on his marks.
The primary reason why he has b een able to achieve his goal inClass 12th CBSE results, is because of his clarity in appro ach that too right from the word go. Sarthak strongly suggests that everyone should decide on a career objective first, and strive hard to achieve it, and very importantly, making sure not to digress. In spite of everything, a straight line is the shortest distance between two points.
His success may have been extraordinary, still the path towards it can be summed up in the age-old adage – ‗Practice makes perfect‘. Though this is nothing new, but he still wanted to share it with everyone. He worked immensely hard and studied between 10 to 15 hours a day for Class 12 CBSE board exams . He got constant guidance from h is parents and teachers and made sure that he learnt from every mistake.
Sarthak‘s main focus was to correct his shortcomings and to reinforce what he already knew. About that, his teachers worked hard and relentlessly, thus making sure that every possible error was taken into consideration.
Another tip he wanted to share with everyone is that, the Internet is n ot just Facebook and Twitter. Internet has boundless opportunities for learning via interactive animations, question banks and video lectures. He made extensive use of these tools when he n eeded to go beyond what the boo ks could offer. This practise gave him required knowledge in quick time and such knowledge from any o ther source in such a less time is practically impossible.
Finally, Sarthak gave a last message to everyone that simply try and give your best shot, and don‘t think too much about the 12th Class results .
Sarthak confessed that the happiness he got from writing his 12th Class Board exams in the best possible way, was far greater than all the glitter that followed his CBSE results. According to him, if you can proudly say that they you h ave done your best, then you are definitely a winner. For everyone, who wants to follow his footsteps, he shared his favourite quo te- ‗Never calculate the height of a mountain before you climb it. When you reach the top , you will realise how low it was‘ – a quote by Hammarskjold. In the end Sarthak wishes everyone a great journey uphill!
How to score 100/100 marks in Maths askIITians

Mathematics can be a nightmare to some students whereas fun for some others. It is basically because of the same reason. You either get it completely right or entirely wrong. It‘s not like a language subject wherein there can be a maybe. And that is also the reason that it is definitely possi ble to score 100/100 marks in maths . How can you score 100/100 marks in maths:
People say that only the students with a rational bent of mind understand mathematics. But it is not so. Mathematics is subje ct which helps in developing a rational thinking and a logical approach in students. A student cannot be made to fall in love with mathematics overnight but following are some tips to improve your score in maths and even help you achieve full marks in maths.
During Exam Preparations:
Make a separate register for theorems, formulae and methodologies: Maths is all about theorems, concepts and
formulae, and it‘s always wise to keep them handy. You can read and brush them up even when you are on the move and this practice also comes to rescue when you are having a last minute revision.
Solve Problems yourself : Whereas it is good to go through and understand different types of problems, it is very
important to solve them yourself. Knowing theories and concept is necessary but to learn their application is inescapable if you want to score full marks in maths. You have to solve each by yourself, minimum 3-4 times over the course of time.
Understand your syllabus: Understanding your portions and the weightage attached to different sections helps you in
deciding how much time to dedicate to each section. For example, if you know that there will be just a 5 marks question from a particular section, you do not have to dedicate a week practicing those sums.
Practice Papers: Practice papers are a good way to mentally prepare yourself for what you are going to get in the
exams. The more you solve these, more confidence you will gain towards your achievement of scoring the highest score. Also, it is important to understand that you need not wait for your syllabus to finish before you start solving these. As you go on finishing different sections, you can find the respective questions from the sample papers and solve them side by side.
Address your problem areas outright: There may be times when you are solving a sample paper and you come
across some questions which you cannot solve. While it is convenient to keep them aside to clear later, but over a period of time these accumulate and become a burden for you.
Time Management: It is not easy to be a maths champion. You must take out some time every day to solve
mathematical problems in order to score 100/ 100 marks in maths , even when you have dedicated a particular day to some other subject. This can range from a quick half an hour of going through your register of formulae and methodologies, or dedicating couple of hours to solve sample papers.
During Examination:
Clean Paper and margin: The cleaner, the better. You should keep in mind that the examiner needs to understand
each and every step how you have arrived at an answer and unfortunately he does not have much time to dedicate on a single problem. Keep your paper free from cutting and overwriting, and draw clean margins to do the rough work. A clean paper also reflects an uncluttered mind.
Marks are in the steps: whenever you go through a solution and understand its rationale, pay special focus on how the
different steps progress. You cannot cram answers and achieve full marks in maths , so just paying heed to the figures in the examples is a waste of your time. Instead you must learn the various steps involved. Remember that even if you attempt and write some steps, you will definitely secure some marks for each step, irrespective of whether your answer is correct or incorrect.
Figures and Graphs: Figures and graphs can fetch you easy marks if made with a little concentration. For this, keep a
ruler which has sharp and smooth side and a pencil which is well sharpened. These, if you have practised well, constitute the simplest parts of the exam and you can aim to finish this as soon as you get your paper.
Finish familiar questions first: Read the question paper thoroughly before you start solving the questions. While it is
natural to be stuck on the questions which you find unfamiliar but you must remember that you have to finish your
examination in a stipulated time. In order to achieve 100/ 100 marks in maths, you much strategize to first finish the questions you know and then move on to the unfamiliar questions.
Revise, revise, and revise: Once you are through with writing the paper, take a deep breath and revise it thoroughly. In
the first revision check whether you have attempted all questions or not. This is important because you might not have solved the questions in a given order. In the second revision check the steps and the rest. If time still remains, go through the sheet once again!
To achieve 100/100 marks in maths , make it a fun experience. Understand the basic concept first and then try so lving as many problems as possible. Remember that there are no shortcuts in maths!

5 Best Tips from Ex-Toppers to Improve Your Performance This CBSE Exam Season Speed doesn‘t really account to your driving skills on roads, the same way it doesn‘t guarantee you success in exams. You must learn to control your speed in every field of life to avoid accidents.
In fact, most students from the past have abided by this rule to perform really well in CBSE Boards. The idea is to stay emotionally stable, have patience, and avoid things th at may cause anxiety. CBSE toppers suggest students to keep a mental balance and avoid last minute preparation. The last minute preparation boosts anxiety level in students that may play a spoilsport in their overall performance during exam.
So to help students perform really well in CBSE, we have bro ught you some ideal tips from ex-CBSE and ICSE toppers.
Tip 1
Students are required to integrate all their subjects and perform well in each one. This sometimes takes a toll in their lives. However, the key is to analyze the situation thoroughly and d etermine an effective method or strategy for revision. Every student
must stick to their basic schedule. They should always have an organized study plan to avoid straying into failure ridden territories.
Tip 2
Students must avoid studying at the last minute. It causes stress and affects their overall performance. Ex-toppers suggest students to take rest just before Boards to keep their minds at peace. In fact, they want parents of students appearing for b oard exams to understand the importance of taking rest and play an i mportant role in their kids‘ academic success.
Tip 3
The best way to perform well in CBSE Boards is to never deviate from basics. In a bid to experiment with new techniques, students tend to compromise with their basics. Study from NCERT books and other materials. Take breaks. Keep revising. Revision should not be done to the point of failure. Take rest in-between and also indulge in your interests.
Tip 4
Students must take some time out of their busy schedules to take small strolls in green parks. A long brisk walk improves memory and students‘ performance by boosting blood circulation to the brain. It is beneficial for students‘ overall health. Don‘t just mug up everything. Study conclusions and other special cases.
Tip 5
Ex-toppers believe that revising is the key to success in CBSE, which should b e done to the p oint of perfection. They should understand that just this is not the end of a life. For example, Khushwant Singh cleared intermediate in his second attempt with only 53%. His academic performance in the college was not up to the mark either. He graduated in third division. But, still, he‘s one of the finest writers India has ever p roduced. He has made the country proud his way.
With all the aforementioned points in place, you must also jot down key po ints of all important points and discuss them with weaker students. Teaching is the best form of learning.

We‘ve all had our lessons in Mathematics in schools and colleges and what haunts us bad still is multiplication of long serpentine trail of digits. But how would your reaction really be if you get to know that what still comes to haunt you back in Maths is a cakewalk for kids (as young as 8) in Japan? Obviously, you can‘t stop cursing yourself. But save that for a while to know what these little Japanese versions of Aryabhatta’s do to make multiplication problems look like a thing of kids. So, what will you do to simply multiply 13 with 12? Undoubtedly, you will follow the pattern that was taught to you in schools — multiply 2 with 3 and 1 and then multiply 1 with 3 and 2 . After that you will sum up the results. Exactly, that‘s the catch here. Japanese kids don‘t follow this traditional Indian method of multiplication in Math. They are taught to do this in very different way by their teachers. They find this method really helpful and swift for multiplications o f really huge numbers.
So, what they really do is draw lines. Yes, d raw lines to multiply! Let‘s take the same example once again.
We got 13 to multiply with 12.
There are two numbers in this problem — 13 and 12.
Let‘s take the first number— 13.
Draw a vertical line for its first digit 1 and 3 vertical lines for another digit 3 with enough space in -between.
Remember that the number to be multiplied (in this case 13) is depicted by vertical lines always.
Now let‘s take another number— 12.
Draw 1 horizontal line on the top for its first digit 1interesecting all four vertical lines. Then, draw 2 more horizontal lines, maintaining enough space from the first horizontal line, for the number‘s another digit 2 again intersecting all four vertical lines.Now, count all the diagonally opposite intersections starting from the point where least number of intersections has been made. Refer to the images below for more clarity.
You will get 1, 5, and 6 intersecting points. Now, combine them to get the answer. Of course, your a nswer will be 156.To multiply numbers with 3 digits, you apply the same rule o f drawing vertical and horizontal lines intersecting each other and counting total numbers of diagonally opposite intersections.
But here you add these numbers of intersections as shown in the second image above. Whew! If you are inspired by this weird but fast method of multiplying numbers then try it on your own peril, because this Japanese method can prove really complicated for multiplying huge numbers.
