How many electrons are in the highest occupied energy level of oxygen?

Answer 1

Oxygen atoms have 6 electrons in the highest occupied energy level. They are two 2s electrons and four 2p electrons.

All elements in Group 16 have 6 valence electrons. For Groups 13-18, subtract 10 from the group number and that gives you the number of valence electrons (the electrons in the highest energy s and p orbitals). The Group 1 elements have one valence electron and the Group 2 elements have two valence electrons. The transition metals can vary in the number of valence electrons. You can't necessarily go by group number for them.

Answer 2

The number of electrons in the outermost energy level of an Oxygen atom is 16.

Answer 3

6
