atoms are the smallest unit of matter which group up to form molecules. atoms have protons, electrons and neutrons. electrons have negative charge and their mass is negligible so their mass does not add to the atom's atomic mass. protons have positive charge and their mass is their number in the periodic table. neutrons have no charge. neutrons and protons make the nucleus. molecules group up to form matter. radicles are simply ions.

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.
