The formation of the oxide ion, O2$$-$$(g) from oxygen atom requires first an exthermic and then an endothermic step as shown below:
O(g) + e$$-$$ $$ \to $$ O$$-$$(g); $$\Delta $$fHo = $$-$$141 kJ mol$$-$$1
O$$-$$(g) + e$$-$$ $$ \to $$ O2$$-$$(g); $$\Delta $$fHo = +780 kJ mol$$-$$1
Thus, process of formation of O2$$-$$ is isoelectronic with neon. It is due to the fact that,
O(g) + e$$-$$ $$ \to $$ O$$-$$(g); $$\Delta $$fHo = $$-$$141 kJ mol$$-$$1
O$$-$$(g) + e$$-$$ $$ \to $$ O2$$-$$(g); $$\Delta $$fHo = +780 kJ mol$$-$$1
Thus, process of formation of O2$$-$$ is isoelectronic with neon. It is due to the fact that,
