Inert Gas

The term inert gas is context-dependent because nitrogen gas and several other noble gases can be made to react under certain conditions.

Unlike noble gases, an inert gas is not necessarily elemental and is often a compound gas. Like the noble gases the tendency for non-reactivity is due to the valence, the outermost electron shell, being complete in all inert gases.

This is a tendency, not a rule, as noble gases and other "inert" gases can react to form compounds.
