Oxidation state is defined as the charge an atom has when electrons are counted according to an agreed-upon set of rules: (l) the oxidation state of a free element (uncombined element) is zero; Ex. "Reduction is the gain of electrons or a decrease in oxidation state by a molecule, atom, or ion." The oxidation number of a free element is always 0. The result is the transfer of one electron from sodium to chlorine, forming the ionic compound NaCl. here to check your answer to Practice Problem 6. In NaCl, sodium has an oxidation number of +1, while chlorine has an oxidation number of −1, by rule 2. For an ion, the oxidation state is the charge. Disproportionation is the name for the reaction where an element simultaneously oxidises and reduces. Hydrogen has an oxidation number of -1 in lithium hydride (LiH). sodium chloride (NaCl) = -1 .
