In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula O− 2. [1] The systematic name of the anion is dioxide (1−).

Superoxide (O2•−) is an oxygen radical and a member of reactive oxygen species. It is an extremely reactive compound formed during single-electron reduction of oxygen. They are …

Superoxide is considered both a radical and a −1 charged anion. It is a relatively unstable molecule, with a half-life of milliseconds, a reasonably strong oxidant, in which case it is …

Feb 15, 2016 · The superoxide ion can be generated chemically from superoxide salts of alkali metals, such as potassium and sodium, and alkaline earth metals, such as strontium and barium.

Jul 22, 2025 · Superoxide is a highly reactive molecule derived from oxygen, often referred to as a free radical or a reactive oxygen species (ROS). It is not an external toxin but a natural …

Sodium superoxide (NaO 2) can be prepared with high oxygen pressures, whereas the superoxides of rubidium, potassium, and cesium can be prepared directly by combustion in air.

Superoxide ions are formed when alkali metals react with molecular oxygen, resulting in compounds like sodium superoxide (NaO2). In superoxides, the oxidation state of oxygen is …

Superoxide is common in biology, reflecting the pervasiveness of O 2 and its ease of reduction. Superoxide is implicated in a number of biological processes, some with negative …

Sep 15, 2025 · Superoxide is a diatomic oxygen, an inorganic radical anion, an oxygen radical and a member of reactive oxygen species. It has a role as a human metabolite, an Escherichia …

Superoxides are formed by heavier alkali metals like cesium, which can be represented as CsO2, where the superoxide ion carries a charge of O2-.
