Question

Why is the electron gain enthalpy of 'F' is less negative than that of 'Cl' ??Although the electron gain enthalpy become less negative as we move down the group....


please answer this question!!!!​

Answer 1

Answer:

here u go

Explanation:

because of the smaller size of fluorine it can't hold more electrons

Answer 2

Answer:

Due to its small size, the electron–electron repulsions in the relatively compact 2p-sub-shell are comparatively large, and hence, the incoming electron is not accepted with the same ease as is the case with larger Cl atom. Consequently, electron gain enthalpy of Cl is more negative than that of F.
