In chemistry, the oxidation state, or oxidation number, is the hypothetical charge of an atom if all of its bonds to other atoms are fully ionic.It describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.
The oxidation states are also maintained in articles of the elements (of course), and systematically in the table {{Infobox element/symbol-to-oxidation-state}}
3 with intermediate oxidation states exist at very low temperatures, decomposing at around 40 K. [21] (In very rare circumstance, fluorine can exist in zero oxidation state other than elemental form - namely, in AuF 7 and in cluster of SF 6 + with helium atoms [22]). Also, the F + 4 cation and a few related species have been predicted to be ...

Beside the lambda notation, as used in the IUPAC nomenclature of inorganic chemistry, [18] oxidation state is a more clear indication of the electronic state of atoms in a molecule. The oxidation state of an atom in a molecule gives the number of valence electrons it has gained or lost. [19]
Redox (/ ˈ r ɛ d ɒ k s / RED-oks, / ˈ r iː d ɒ k s / REE-doks, reduction–oxidation [2] or oxidation–reduction [3]: 150 ) is a type of chemical reaction in which the oxidation states of the reactants change. [4] Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a ...
Oxidation is better defined as an increase in oxidation state of atoms and reduction as a decrease in oxidation state. In practice, the transfer of electrons will always change the oxidation state, but there are many reactions that are classed as "redox" even though no electron transfer occurs (such as those involving covalent bonds). [28] [29]
It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn 2+ and Mg 2+ ions are of similar size.
