Vedclass · Answer

(D) Electron gain enthalpy $(\Delta H_{eg})$ is the energy released when an electron is added to a neutral gaseous atom or ion.For species with a positive charge,the attraction for an incoming electron is significantly higher due to electrostatic forces.Comparing the given species: $F^{-}$,$O$,$O^{-}$,and $Na^{+}$.$Na^{+}$ is a cation with a high positive charge,which exerts a strong electrostatic attraction on the incoming electron,making the process highly exothermic.Therefore,$Na^{+}$ has the most negative (maximum) electron gain enthalpy.
