Although Fluorine has the highest electronegativity, Chlorine has the highest electron affinity and this is because the considerable repulsion in the tightly packed 2p subshell of Fluorine.

Chlorine belongs to third period and group-17.

Chlorine has the highest electron affinity because of high repulsion. For better understanding you can also search electron affinity along a period/group
