An O2 molecule has 12 valence electrons. oxygen is in the 6th group of the periodic table, therefor it has 6 valence electrons.

Two oxygen atoms in a oxygen molecule share two electrons. Oxygen atoms only have 6 valence electrons (electrons in the outer shell). They want 8 electrons so they need to steal two or share two.
