...A general term for the five elements in group VI (group VIB) of the periodic table: oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po). Also called the oxygen family. Since polonium is radioactive and oxygen has properties quite different from other elements, the remaining three elements are sometimes called the sulfur family.
