Question

Why is the gain of enphatly of F less than that of association?

Answer 1

Answer:

"Fluorine atom is small in size and suffers with interelectronic repulsions between seven valence electrons. The added electron experiences much repulsion on smaller F. Hence its electron gain enthalpy is less."

Answer 2

Answer:

hiiiii mate...

The negative electron gain enthalpy of fluorine is less than that of chlorine. It is due to small size of fluorine atom. As a result, there are strong interelectronic repulsions in the relatively small 2p orbitals of fluorine and thus, the incoming electron does not experience much attraction.
