The electronic configuration for the oxygen atom is [math]1s^2 2s^2 2p^4[/math]. It must acquire 2 electrons to become an ion with a charge of -2 . Thus the electronic configuration for an [math]O^{2 -}[/math] ion is
Oxygen atom has the outer electronic configuration of 2S 2 2p 4, with 4 reactive electrons at its outer shell. The molecular oxygen with 0 oxidation state is highly stable due to the participation of each of two electron-pairs donated by the two atoms of oxygen. Thus, the diatomic molecular oxygen contains one sigma- and one pi-bond in its structure.
