Oxygen is in group 16 so it has 6 valence electrons. In order to have a full outer shell, and satisfy the octet rule, it needs 2 more valence electrons to have a full outer shell.

Oxygen has a total of 6 valence electrons; 2 in the 2s sublevel and 4 in the 2p sublevel. It needs two additional 2p electrons to fill its octet.
