Why oxygen is a divalent element whereas sodium is monovalent element?

Question asked by: gsbiruly20

Asked on: 09 Jul 2010

This is due to the electronic (electron) configuration of the lowest energy shell, or outer electrons.

There are two spare parts of the outer shell of oxygen therefore it can increases its stability by having two extra electrons whilst sodium just has one electron to donate to have a full outer shell so it will just give the one away.
