Key Points
The oxidation number of an atom is the charge that would exist on the atom if the bonding were completely ionic.
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.
Atoms with d-shell electrons can have several different oxidation numbers.
In complex ions or molecules, the oxidation numbers of these atoms can be calculated if we assume that the oxidation numbers of the other atoms in the species are fixed.
The oxidation numbers of metals with more than one oxidation state are represented by Roman numerals.
Key Terms
oxidation number: The net sum of the negative, less the positive, charges on an atom.
roman numeral: A numeral represented using a Roman system involving the letters I, V, X, L, C, D, and M.
18 electron rule: Rule used primarily for predicting formula for stable metal complexes; transition metals can accomodate at most 18 electrons in their valence shells.
