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 is neutral, all atoms are. Oxygen can have a charge of 2- AFTER it has bonded with something in group 2 like calcium. This is because oxygen only has 6 electrons on its outer shell, so if it bonds with something with 2 electrons in its outer shell (calcium is group 2) it then becomes stable.
