Noble gas - Wikipedia History. Noble gas is translated from the German noun Edelgas, first used in 1898 by Hugo Erdmann to indicate their extremely low level of reactivity. The name makes an analogy to the term 'noble metals', which also have low reactivity.The noble gases have also been referred to as inert gases, but this label is deprecated as many noble gas compounds are now known.
