WebThe phrase noble gas comes from the German world Edelgas, used first in 1898 by Hugo Erdmann, the same year radon was first identified. We now know that several of these elements are quite abundant on earth. Helium is the second most abundant element in the universe, after hydrogen. WebThe noble gas elements do not react with other elements as they are less electronegative and unable to attract the lone pair of electrons from noble elements. Some of the examples of noble gas compounds are XeF2 , XeF4 , XeF6 , XeO3 , XeOF2 etc. Due to this, the noble gases form compounds with fluorine and oxygen only.

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.
