Noble gas - Wikipedia

The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). Oganesson (Og) is a synthetically produced highly radioactive element, variously predicted to be another noble gas, or to break the trend and be reactive, due to relativistic effects.
