The chalcogens are the chemical elements in group 16 of the periodic table. This group is also known as the oxygen family. It consists of the elements oxygen , sulfur , selenium , tellurium , and the radioactive element polonium . The chemically uncharacterized synthetic element livermorium is predicted to be a chalcogen as well. Often, oxygen is treated separately from the other chalcogens, sometimes even excluded from the scope of the term "chalcogen" altogether, due to its very different chemical behavior from sulfur, selenium, tellurium, and polonium. The word "chalcogen" is derived from a combination of the Greek word khalk?s principally meaning copper , and the Latinised Greek word gen?s, meaning born or produced.
