<P> 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 . Rare gases is another term that was used , but this is also inaccurate because argon forms a fairly considerable part ( 0.94 % by volume , 1.3 % by mass ) of the Earth 's atmosphere due to decay of radioactive potassium - 40 . </P>
