Question

explain electron gain enthalpy with the help of an example chlorine
​

Answer 1

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

Answer 2

Answer. this is an exception and chlorine has higher electron gain enthalpy than Fluorine. ... This makes incoming of another electron not very favourable. Even though fluorine has large negative electron gain enthalpy but for chlorine its even more negative
