Knowing the electron gain enthalpy values for O → O− and O → O2�

1.	Knowing the electron gain enthalpy values for O → O− and O → O2− as −141 and 702 kJ mol−1 respectively, how can you account for the formation of a large number of oxides having O2− species and not O−? (Hint: Consider lattice energy factor in the formation of compounds).
Answer» Knowing the electron gain enthalpy values for O → O⁻ and O → O²⁻ as −141 and 702 kJ mol⁻¹ respectively, how can you account for the formation of a large number of oxides having O²⁻ species and not O⁻? (Hint: Consider lattice energy factor in the formation of compounds).
