C-2,4

N2– 2

O2– 2

F2- 2

Ne- 1

Na- 1

Mg- 1

Al-1

Answer 2

Atomicity of Ozone is 3

Explanation:

• Atomicity = Total number of atoms in Molecule.  

For eg. Every Molecule of O = 2 Atoms.  

• Hence,  atomicity of oxygen = 2.

Earlier,  we used to say that valency is nothing but the atomicity of a molecule of element.  

(a) Atomicity of Oxygen -2

(b) Atomicity of Ozone-3

(c) Atomicity of Neon-1

(d) Atomicity of  Sulphur-8

(e) Atomicity of  Phosphorus-4

(f) Atomicity of Sodium-1
