7. Inert gas - Wikipedia

   en.wikipedia.org/wiki/Inert_gas

   The term inert gas is context-dependent because several of the noble gases can be made to react under certain conditions. Helium, Neon, Argon, Krypton, Xenon, Radon are the six inert ( noble ) gases Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2, 1% Ar in air [2]) and low relative cost.
