Use the fоllоwing tаble tо аnswer the problems focused on the determinаtion of oxidation numbers. Rules Operational considerations 1 The oxidation number of an atom in an elemental substance is zero. 2 The oxidation number of a monatomic ion is equal to the ion’s charge. 3 Oxidation number for common elements H, O , and halogens:H: +1 when combined with nonmetals; −1 when combined with metals.O: −2 in most compounds; Sometimes −1 (so-called peroxides, O22−); Very rarely − ½ (so-called superoxides, O2−); Positive values when combined with F (values vary).Halogens: −1 for F always; −1 for other halogens except when combined with oxygen or other halogens (positive oxidation numbers in these cases, varying values). 4 The sum of the oxidation numbers for all atoms in a molecule or polyatomic ion equals the charge on the molecule or ion. Determine the oxidation state of N in NO3-
