In simple ions, the oxidation number of the atom is the charge on the ion. In a molecule or compound, the oxidation number is the sum of the oxidation numbers of its constituent atoms. The oxidation number of a monatomic ion equals the charge on that ion, e.g., Na + and Cl –. Some elements have the same oxidation number in nearly all their compounds. Elements in periodic group IA have oxidation numbers of +1, and elements in periodic group IIA have oxidation numbers of +2, e.g., Na +. An atom’s oxidation number (or oxidation state) is the imaginary charge that the atom would have if all of the bonds to the atom were completely ionic. Oxidation numbers can be assigned to the atoms in a reaction using the following guidelines: An atom of a free element has an oxidation number of.

Se hela listan på 2020-04-14 · The oxidation number for NO3, or nitrate, is -1. This is because oxygen always has an oxidation number of -2. The three oxygen atoms have a combined oxidation of -6, corresponding to their electromagnetic charge and the lone nitrogen has a charge, or oxidation number, of +5. Oxidation state definition is - a positive or negative number that represents the effective charge of an atom or element and that indicates the extent or possibility of its oxidation —called also oxidation number.
