Molecule is the smallest unit of element or compound which has independent existence. When two or more elements combine together in order to have independent existence. The elements combine together in whole no. They do so in order to get stability. Ex- O2, Cl2 and N2 etc…
When atoms of different element joins together in a definite proportion to form molecules of compound. Eg. H2O in water 2 atoms of hydrogen combines with 1 atom of oxygen atom. Q-If formula of Sulphuric Acid is H 2SO4 then find out the no. of various elements in it. Is this molecule of compound?
