    The mineral breithauptite (NiSb) contains nickel and the semimetal antimony, which acts as the electronegative, nonmetallic element of the compound. Breithauptite is thus an antimonide. The mineral calaverite (AuTe 2), in turn, contains the metallic element gold and the semimetal tellurium, which provides an anion; calaverite is a telluride.
