noble gas (plural noble gases )
( chemistry ) Any of the elements of group 18 of the periodic table , being monatomic , usually inert (with very limited exceptions ), and gaseous at familiar temperatures.
Synonyms: aerogen , rare gas
Hypernyms: inert gas < gas
When the term was coined, all known group 18 elements were unreactive gases . This may not be true for the recently discovered superheavy element oganesson , though experiments cannot yet be carried out because of its short lifetime. Chemists usually include oganesson as a noble gas to extend the term to all of group 18, though those specializing in the chemistry of superheavy elements may exclude it.
