Answer 2

Answer is 3,8,4,1 or Option (d)

Explanation:

• Atomicity = Total Number of Atoms of Molecule.

Example - Oxygen Molecule = 2 atoms of oxygen

Hence, Giving Oxygen an Atomicity of 2

Earlier,

• Atomicity was equivalent to valency as per the scientists,  

1. The atomicity of Ozone (O_3) is 3
2. The atomicity of Sulphur (S)- 8
3. The atomicity of Phosphorus (P)- 4
4. The atomicity of Argon(noble gas, Ar)- 1
