The first ionisation enthalpies (in eV) of N & O are respectively given by :
A
14.6, 13.6
B
13.6, 14.6
C
13.6, 13.6
D
14.6, 14.6
Answer
14.6, 13.6
Explanation
Solution
Due to stable half filled electronic configuration of outer most shell of N, it has higher ionisation energy than O which has partially filled electron configuration of outer most shell.
