inert gases
Helium and argon
Inert gases are elements that resist chemical reaction with other substances—helium, neon, argon, krypton, xenon, and radon.
Their atomic structure makes them extremely stable, so they don't readily form compounds.
Also called noble gases.
The term appears in chemistry and industrial contexts: Welding often uses inert gases to shield the work from oxygen.
