Which of the elements has the maximum electron affinity

A$$F$$
B$$Cl$$
Correct Answer
C$$Br$$
D$$I$$

Solution

Fluorine has low electron affinity than chlorine. This is because due to smaller size of fluorine and electrons are more closely bound together so that incoming electron feels repulsion so additional energy is required to hold the incoming electron. That's why fluorine has smaller electron affinity than chlorine. So chlorine has maximum electron affinity.
