Question

electron affinity is maximum in:
(a) alkali metals
(b) alkaline earth metals
(c) halogens
(d) inert gases​

Answer 1

The halogens, directly to the left of the noble gases, readily gain electrons and react with metals.so electron affinity is maximum for halogens

Answer 2

Halogens have maximum electron affinity bcoz it is just 1 electron short of noble gases
So it has large electron affinity
