Question

F nd cl who has high electron gain enthalpy why

Answer 1

f is more high electron gain enthalpi

Answer 2

Answer:

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.
