The inert gases are

A

Polyatomic

B

Triatomic

C

Diatomic

D

Monoatomic

Text Solution

Verified by Experts

The correct Answer is:
D
All the noble gases are monoatomic, colourless and odourless gases. Their monotomic nature is due to the stable outer configuration `ns^(2),np^(6)` of their atoms. As a result, they do not enter into chemical combination even amongst themselves.
