SUMMARY
The discussion centers on the exothermic nature of electron gain enthalpy, specifically why atoms release energy upon gaining electrons. It is established that the net attractive force between an atom and an incoming electron results in energy release, contrasting with the endothermic process of ionization energy, which requires energy input to overcome nuclear attraction. Halogens, due to their smaller atomic size and higher nuclear charge, exhibit a greater release of energy when gaining electrons compared to other elements.
