==Nomenclature==
The [[trivial name]] ''ozone'' is the most commonly used and [[preferred IUPAC name]]. The systematic names ''2λ<sup>4</sup>-trioxidiene''{{dubious|date=February 2019}} and ''catena-trioxygen'', valid [[IUPAC]] names, are constructed according to the [[chemical nomenclature#Substitutive nomenclature|substitutive]] and [[chemical nomenclature#Additive nomenclature|additive nomenclatures]], respectively. The name ''ozone'' derives from ''ozein'' (ὄζειν), the [[Greek language|Greek]] neuter present participle for smell,<ref>{{cite web |title=ozone (n.) |publisher=Merriam-Webster |website=Online Etymological Dictionary |url=https://www.etymonline.com/search?q=ozone%20,%20https://www.merriam-webster.com/dictionary/ozone |access-date=24 May 2023}}</ref> referring to ozone's distinctive smell.

In appropriate contexts, ozone can be viewed as [[trioxidane]] with two hydrogen atoms removed, and as such, ''trioxidanylidene'' may be used as a systematic name, according to substitutive nomenclature. By default, these names pay no regard to the radicality of the ozone molecule. In an even more specific context, this can also name the non-radical singlet ground state, whereas the diradical state is named ''trioxidanediyl''.

''Trioxidanediyl'' (or ''ozonide'') is used, non-systematically, to refer to the substituent group (-OOO-). Care should be taken to avoid confusing the name of the group for the context-specific name for the ozone given above.
