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 molecul… 2.1Metal oxides 2.2Non-metal oxides 3Structure Toggle Structure subsection 3.1Molecular oxides 4Reactions Toggle Reactions subsection 4.1Reduction 4.2Hydrolysis and dissolution 5Nomenclature and formulas 6See also 7References Toggle the table of contents Toggle the table of contents Oxide … See more An oxide is a chemical compound containing at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O ion with oxygen in the See more Oxides are associated with all elements except a few noble gases. The pathways for the formation of this diverse family of compounds are correspondingly numerous. See more Reduction Reduction of metal oxide to the metal is practiced on a large scale in the production of some metals. Many metal oxides convert to metals simply by heating, (see Thermal decomposition). For example, See more • Other oxygen ions ozonide, O−3, superoxide, O−2, peroxide, O2−2 and dioxygenyl, O+2. • Suboxide • Oxohalide • Oxyanion See more Oxides are extraordinarily diverse in terms of stoichiometries (the measurable relationship between reactants and chemical equations of a equation or reaction)) and in terms of the structures of each stoichiometry. Most elements form oxides of more than … See more Oxides have a range of structures, from individual molecules to polymeric and crystalline structures. At standard conditions, oxides may range from solids to gases. Solid oxides of metals usually have polymeric structures at ambient conditions. See more The chemical formulas of the oxides of the chemical elements in their highest oxidation state are predictable and are derived from the number of valence electrons for that element. Even the chemical formula of O4, tetraoxygen, is predictable as a See more

WebThe charge on the ion is therefore equal in magnitude to the number of electrons gained to reach a full octet of eight valence electrons. Mathematically, we can calculate the magnitude of the charge by subtracting the number of valence electrons in the neutral atom from eight. WebIf an ion is made up of only one type of atom (each holding some net charge, positive or negative), it can be referred to as an atomic ion or a monoatomic ion. On the other hand, … heard museum guild website
