Noble Gases[edit] The noble gases are in Group 18 (8A). These elements contain ns2, np6 valence shell electronic configuration, therefore, they do not have a tendency to react with other elements to form compounds
They are helium, neon,argon, krypton, xenon, and radon.
They were once called inert gases because they were thought to be completely inert—unable to form compounds
