Inert gas

An inert gas was the former term for the elements of Group 8A (IUPAC notation: 18) of the periodic table, now referred to as noble gases.

In general an intert gas is any gas that is nonreactive.

Helium, neon and argon are the only true elemental inert gases as they do not form any true compounds with other elements like the heavier noble gases.
