The word atom comes from the word  Atomos. 
Atomicity refers to the sum total
of atoms of same or different
elements present in a molecule
Valency is the combining capacity of an  element or of a radical.

molecule are made up of atoms.
atoms are the smalllest possible unit ,they do not have independent existence.
molecule have an indepentend existence.
history is known from grade 6
