WebDec 30, 2016 · Explanation: Oxygen has atomic number eight. This means that the nuclei of all oxygen atoms have eight protons. A neutral oxygen atom will also have eight electrons. In an oxygen ion with a 2− charge, the number of protons is still 8, but the number of electrons is 10. This results in the oxygen ion having an octet (8) of valence electrons.
