Vedclass · Answer

(A) Fluorine has a lower electron affinity than chlorine due to the smaller atomic radius of fluorine and high electron density.There are strong interelectronic repulsions in the relatively compact $2p$ subshell of fluorine.Consequently,the incoming electron experiences significant repulsion,which reduces the overall energy released during electron gain.

Fluorine has lower electron affinity than chlorine because of
