Explanation

Noble gases (Group 18 elements) are characterized by their inertness due to having a complete valence shell of electrons. Helium, neon, argon, krypton, xenon, and radon are all very unreactive under normal conditions. 'Inert' means chemically non-reactive, which is the defining property of noble gases.
