Where is Group 16 on the periodic table?
oxygen family
Group 16 is the third last group in the periodic table. This group is called the oxygen family or the chalcogens. The elements in this group are oxygen, sulfur, selenium, tellurium, polonium and livermorium. The first three elements are nonmetals and the last two are semimetals.
