oxidation number of group 18

Group 15 has a number of 3-. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component. Take a typical compound – \(FeCl_3\), for instance. 8 [He] 2s² 2p⁴. Copyright © 2020 Multiply Media, LLC.
