1. Superoxide

   In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula O−2. The systematic name of the anion is dioxide(1−). The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O2, which occurs widely in nature. Molecular oxygen (dioxygen) is a diradical containing two unpaired electrons, and superoxide results from the addition of an electron which fills one of the two degenerate molecular orbitals, leaving a charged ionic species with a single unpaired electron and a net negative charge of −1. Both dioxygen and the superoxide anion are free radicals that exhibit paramagnetism. Superoxide was historically also known as "hyperoxide".

1. superoxide

   A superoxide is a molecule or ion that contains oxygen in an oxidation state of -1. It is formed by the reduction of molecular oxygen (O2) in which one electron has been added. Superoxides are highly reactive due to their unpaired electrons and can cause damage to cells. They are also involved in various biological processes including respiration and immune response.

1. Superoxide

   A superoxide, also known by the obsolete name hyperoxide, is a compound that contains the superoxide anion with the chemical formula O2−. The systematic name of the anion is dioxide. Superoxide anion is particularly important as the product of the one-electron reduction of dioxygen O2, which occurs widely in nature. Whereas molecular oxygen is a diradical containing two unpaired electrons, the addition of a second electron fills one of its two degenerate molecular orbitals leaving a charged ionic species with single unpaired electron and a net negative charge of -1. Both dioxygen and superoxide ion are free radicals that exhibit paramagnetism.
