Group 16 is the oxygen family. It consists of the elements oxygen, sulfur, selenium, tellurium, and polonium. Each has six of the desired eight electrons required for the octet in its highest energy level.
Best Answer: All atoms are neutral. An oxygen atom is neutral. The oxygen molecule, O2 is neutral. The oxygen ion has taken on 2 additional electrons from another atom to become the O^-2 ion. Oxygen, from column 6 has 8 electrons, 2 in the first energy level[now that level is full] and 6 in the outer energy level.
