The process requiring absorption of energy is:

A

`N to N^(-)`

B

`F to F^(-)`

C

`Cl to Cl^(-)`

D

`H to H^(-)`

Text Solution

Verified by Experts

The correct Answer is:
A
Nitrogen has stable `2p^(3)` configuraiton and also due to high `e^(-)` charge density at outermost orbital it requires energy to add one extra `e^(-)` in its outer most shell i.e., its first electron gain enthalpy is positive.
