Vedclass · Answer

(C) Energy is released when an electron is added to a neutral atom to form an anion,a process known as electron gain enthalpy. For the process $Cl + e^{-} 	o Cl^{-}$,the electron gain enthalpy is negative,meaning energy is released. In the case of $O^{-} + e^{-} 	o O^{2-}$,energy is absorbed because of the strong electrostatic repulsion between the incoming electron and the negatively charged $O^{-}$ ion. Processes $Cl 	o Cl^{+} + e^{-}$ and $Ne + e^{-} 	o Ne^{-}$ are endothermic processes requiring energy input.
