    Please explain me atomicity in easy words.

    Dear Student,
    The number of atoms bonded in a molecule of an element is called its atomicity. Molecules of elements can be classified by its atomicity as follows-
    1. Monoatomic molecule- elements having only one atom in their molecule, e.g.  All noble gases – Helium (He), Neon (Ne), Argon (Ar), etc.) are monoatomic molecules.
    2. Diatomic molecule- elements having two atoms in their molecule, e.g.  Hydrogen (H2), Nitrogen (N2), Oxygen (O2), Chlorine (Cl2), etc.
    3. Triatomic molecule- elements having three atoms in their molecule, e.g.  Ozone (O3)
    4. Tetratomic molecule- elements having four atoms in their molecule, e.g.  Phosphorus (P4)
    v. Polyatomic molecule- elements having more than four atoms in their molecule, e.g.   Sulphur (S8)
