Which one of the following elements has the highest first ionisation potential?

A

Boron

B

Carbon

C

Nitrogen

D

Oxygen

Text Solution

Verified by Experts

The correct Answer is:
C
Among the four elements (i,e., B, C, N, O), nitrogen has half filled electronic configuration `(1s^(2) 2s^(2) 2p^(3))`. So, it has high IP.
