Helium family group

The second lightest element (only hydrogen is lighter), helium is a colourless, odourless, and tasteless gas that becomes liquid at −268.9 °C (−452 °F). Any of the six colorless, odorless, minimally chemically reactive gaseous elements found in group 18 of the periodic table. The gases are argon, helium, krypton, neon, radon, and xenon. Synonym: inert gas.

Because their valance electrons are all paired there is little bonding of these electrons. though some of the larger noble gases do form some bonds. Any of the six colorless, odorless, minimally chemically reactive gaseous elements found in group 18 of the periodic table. The gases are argon, helium, krypton, neon, radon, and xenon.

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.
