The term chalcogen was first used by the Wilhem Biltz research group at the University of Hannover in Germany. Sepcifically, one man named Werner Fischer coined this group the chalcogens. In Greek, the word means "copper-former" but this translation does not fit the group. The chalcogens have nothing to do with copper, so the translation is more commonly "ore former."
The chalcogens, the oxygen group, is located in column 16 of the periodic table. It contains the elements oxygen, sulfur, selenium, tellurium, polonium, and ununhexium (O, S, Se, Te, Po, and Uuh, respectively). These elements all contain six valence electrons and form 2- ions. The physical properties of this group vary dramatically. Oxygen is a colorless gas while sulfur is a yellow solid. Tellurium is a silver metalloid, and selenium is black.
