Explanation:
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.
hope this help you!!!

Explanation:
Halogens have highest negative value ofelectron gain enthalpy . here Cl &F both are halogens but electron gain enthalpy of Cl isgreater than F because of very small size of Fwhich causes inter electronic repulsion among its electrons. ... as a result there are strongelectron repulsion in the 2p orbital.
