Question

2. a) Fluorine has less negative electron gain enthalpy than that of Chlorine.
b.Would you expect the second electron gain enthalpy of O as positive, more negative or less negative than the first ? justify your answer


if there is anyone who knows please help me

​

Answer 1

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
