Dear student,

When an oxidation number is assigned to the element, it does not imply that the element in the compound acquires this as a charge, but rather that it is a convenient number to use for balancing chemical reactions. The guidelines for assigning oxidation states (numbers) are given below:

  • The oxidation state of any element such as Fe, H2, O2, P4, S8 is zero (0).
  • The oxidation state of oxygen in its compounds is -2, except for peroxides like H2O2, and Na2O2, in which the oxidation state for O is -1.
  • The oxidation state of hydrogen is +1 in its compounds, except for metal hydrides, such as NaH, LiH, etc., in which the oxidation state for H is -1.
  • The oxidation states of other elements are then assigned to make the algebraic sum of the oxidation states equal to the net charge on the molecule or ion.
  • The following elements usually have the same oxidation states in their compounds:
    • +1 for alkali metals - Li, Na, K, Rb, Cs;
    • +2 for alkaline earth metals - Be, Mg, Ca, Sr, Ba;
    • -1 for halogens except when they form compounds with oxygen or one another.
