Word HistoryWhat makes a noble gas so noble? Thenoble gasesare a group of six chemical elements, normally occurring in gaseous form, that do not react chemically with other elements or chemical compounds except very rarely. Helium and neon are two familiar examples. The fact that the noble ga...
What are the Noble Gases? The noble gases are a group of non-metals consisting of helium, neon, argon, krypton, xenon and radon. Radon is radioactive. The gases grow denser down the group, because the mass of the atom increases.

Noble Gases, being a subset of Inert Gases, share the characteristic of being unreactive, but they have their unique position in the periodic table. 10 One might encounter Inert Gases outside of the Noble Gases group. For instance, nitrogen (N2) is often considered an inert gas under ...
