Question

Electron gain enthalpy of f is less negative than cl give reason

Answer 1

because metal donates the. electron. from it's valence shell and non metal accept the electron so.

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.
