Rules for oxidation state

  • The oxidation state of an uncombined element is zero. This applies regardless of the structure of the element:C, Xe, Cl2, S8, and large structures of carbon or silicon each have an oxidation state of zero.
  • The sum of the oxidation states of all the atoms or ions in a neutral compound is zero.
  • The sum of the oxidation states of all the atoms in an ion is equal to the charge on the ion.
  • The more electronegative element in a substance is assigned a negative oxidation state. The less electronegative element is assigned a positive oxidation state. Remember that electronegativity is greatest at the top-right of the periodic table and decreases toward the bottom-left.
