Aug 8, 2024 · The meaning of NOBLE GAS is any of a group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon and that exhibit great stability and extremely low reaction rates —called also inert gas.
Definition: What are noble gases? Noble gases belong to a special category of elements in the periodic table that are inert, non-metal, and non-reactive. The special feature of these elements is that their outermost orbital is complete and do not have any free electrons to participate in chemical reactions.
