Answer 2

ATOMICITY -

1. Monoatomic

• Molecules that have only one atom.
• Example - All noble gases such as He, Ar, Ne.

2. Diatomic

• Molecules that are made of two atoms bonded together.
• Example - All halogen, $N_2, H_2, O_2, Cl_2.$

3. Polyatomic

• Molecules made of three or more atoms bonded together.
• Example - $P_4, S_8, SO_2.$
