Inert gases are made up of?

Inert gases are the noble gases. These elements have full outer electron shells, which makes them extraordinarily stable and highly unreactive under normal conditions. The gases in this family include helium, neon, argon, krypton, xenon, and radon. Nitrogen, while diatomic N2 is comparatively unreactive, is not a noble gas and does not share that full-shell stability. So inert gases are made up of the noble gases, not nitrogen. The idea is to recognize that the group’s defining feature is their full electron shells and resulting chemical inertness.
