Helium and neon, the two lightest noble gases, have been traditionally positioned by IUPAC in the Group 18 of the Periodic Table of Elements, together with argon, and other unreactive or moderately reactive gaseous elements (krypton, xenon, radon), and oganesson. Helium, along with neon, argon, krypton, xenon, and radon, is an inert gas (also known as a noble gas) – that is, it does not normally react with other elements to form chemical compounds.
