The formation of the oxide ion, O2- (g), from oxygen atom requires first an exothermic and then an endothermic step as shown below:
$\text{O(g)}+\text{e}^-\xrightarrow{\ \ \ \ \ \ \ \ \ \ \ }\text{O}^-(\text{g}),\ \Delta\text{H}^\ominus=-141\text{kJ}\text{ mol}^{-1}$
$\text{O(g)}+\text{e}^-\xrightarrow{\ \ \ \ \ \ \ \ \ \ \ }\text{O}^{-2}(\text{g}),\ \Delta\text{H}^\ominus=+780\text{kJ}\text{ mol}^{-1}$
Thus process of formation of O2- in gas phase is unfavourable even though O2- is isoelectronic with neon. It is due to the fact that:
