Electron affinity is maximum for

A

Cl

B

F

C

Br

D

I

Text Solution

Verified by Experts

The correct Answer is:
A
Electron affinity is energy released when electron is added to isolated gaseous atom. Its value decreases down the group. So electron affinity of F should be highest among halogens but due to its smaller size electron affinity of Cl is more than F.
`:.` Cl has highest electron affinity.
