An atom is a smallest particle of element which can take part in a reaction and is considered the basic unit of matter. Eg:- O, H, HCl are atoms.

A molecule is the smallest particle of a substance that can normally exist separately and retain the characteristics of the substance.

Eg:- O2, H2, Cl2 are molecules.
