noble gases
group of chemical elements in column 18 of the periodic table, that tend to be chemically inert and thus form odorless, colorless, monatomic gases with low reactivity; consists of helium, neon, argon, krypton, xenon, radon, and possibly oganesson
AI overview
Noble gases are a group of chemical elements—including helium, neon, and argon—that are naturally odorless, colorless gases and rarely react with other elements because of their chemical inertness. Their low reactivity makes them useful for applications where other gases might unwantedly combine with materials, such as in lighting, welding, and scientific research.

The noble gases (historically the inert gases, sometimes referred to as aerogens) are the members of group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) and, in some cases, oganesson (Og). Under standard conditions, the first six of these elements are odorless, colorless, monatomic gases with very low chemical reactivity and cryogenic boiling points. The properties of oganesson are uncertain.
