ORANGE BOOK DEFINITION

IUPAC. Analytical Division. Compendium of Analytical Nomenclature (the Orange Book). Definitive Rules, 1979 (see also Orange Book 2023)

Negative Ion

An atom, radical, molecule or molecular moiety in the vapour phase which has gained one or more electrons, acquiring thereby a negative charge. The term anion is not recommended because of its connotations in solution chemistry.
