Oxidation (Oxidation number) oxidation. Is the Coulomb Or assumed charge of the atom or ion. Based on the number of electrons to or received by the established criteria.
, when all the elements together in a compound electrons elements. The oxidation number is positive and is equal to the number of electrons. The elements of the electron Will have a negative oxidation number And is equal to the number of electrons that. , for example, when a compound of Zn. To the electron 2 into a Zn2 +, so it has an oxidation number of +2. Na is the Na + electron 1 has an oxidation number = +1. Al as Al3 + electron 3 is the oxidation number = +3. Cl is Cl- electrons 1 Therefore, the oxidation number = -1. O 2 as an electron O2- has oxidation number = -2.
