The first ionisation potential in electron volts of nitrogen and oxygen atoms are respectively given by

A

14.6,13.6

B

13.6,14.6

C

13.6,13.6

D

14.6,14.6

Text Solution

Verified by Experts

The correct Answer is:
A
First ionisation potential of nitrogen is more than oxygen. It is due to exactly half filled p-subshell in N.Thus ionisation potentials (in eV) of N , O are 14.6, 13.6 respectively.
