Which of the following elements will have the highest electron affinity?

Options

AChlorine
BNitrogen
CPhosphorus
DFluorine

Correct answer

A. Chlorine

Step-by-step solution

In general, electron affinity increases from left to right in a period and decreases down the group. But due to interelectronic repulsions in small sized
