Ionization enthalpy `[IE_1]` of O is less than that of N - explain.

Text Solution

Verified by Experts

`rarr` Oxygen has electronic configuration `1s^(2) 2s^(2) 2p^(4)`

`rarr` Nitrogen has electronic configuration `1s^(2) 2s^(2) 2p^(3)`

`rarr` Nitrogen has half filled shell and is stable so more amount of energy is required to remove an electron, than in oxygen. Hence IE, of .O. is less than that of .N..
