== Nomenclature ==
The linkage between the oxygen molecules is known as a '''peroxy group''' (sometimes called '''peroxo group,''' '''peroxyl group, of peroxy linkage'''). The nomenclature of the peroxy group is somewhat variable,<ref>{{GoldBookRef|title=peroxides|file=P04510}}</ref> and exists as an exception to the rules of naming polyatomic ions. This is because, when it was discovered, it was believed to be monatomic.<ref>{{Cite web |date=2004 |title=Nomenclature |url=https://chemed.chem.purdue.edu/genchem/topicreview/bp/ch2/names.html |access-date=March 25, 2024 |website=Purdue Division of Chemical Education}}</ref>  The term was introduced by [[Thomas Thomson (chemist)|Thomas Thomson]] in 1804 for a compound combined with as much oxygen as possible,'''''<ref>{{Cite book |last=Thomson |first=Thomas |title=A System of Chemistry |date=1804 |publisher=Bell and Bradfute |edition=2nd |volume=1 |location=Edinburgh |publication-place=Edinburgh |publication-date=1804 |pages=division 1, page 103 |language=English |chapter=4 |via=Google books}}</ref>''''' or the oxide with the greatest quantity of oxygen.<ref>{{Cite web |last= Harper, Douglas. |title=Peroxide |url=https://www.etymonline.com/word/peroxide#:~:text=peroxide%20(n.),effective%20bleaching%20agent%20for%20hair). |website=Online Etymology Dictionary}}</ref>
