(C) The process of adding an electron to a neutral atom to form an anion is called electron gain enthalpy. For the first electron addition ($F 	o F^-$,$Cl 	o Cl^-$,$O 	o O^-$,$H 	o H^-$),energy is generally released. However,the addition of a second electron to a uninegative anion (like $O^- + e^- 	o O^{2-}$) requires the absorption of energy to overcome the strong electrostatic repulsion between the incoming electron and the negatively charged anion. Therefore,the process $O 	o O^{2-}$ involves two steps: $O + e^- 	o O^-$ (energy released) and $O^- + e^- 	o O^{2-}$ (energy absorbed),where the second step requires significant energy input.
