O.S. of O = -2
The oxidation number of Cl in potassium chlorate (KClO3) is +5. This is because the oxidation number of K is +1 and the oxidation number of O is -2. By using the sum of the oxidation numbers in the compound, the oxidation number of Cl can be calculated to be +5.
The chlorate ion is ClO3-. Some text books say that the oxidation number of the whole ion is equal to the charge, so in this cas it would be -1. However most teachers would sya that oxidation numbers only refer to atoms. So working out the oxidation numbers:- oxygen is -2, (using the rule, or if you use the he electronegativity method- gives the same answer as O is more electronegatoive than Cl) the sum of oxidation numbers of Cl and O are -1 (the charge on the ion) - I'll call the oxidation number of Cl OxCl -1 =OxCl + (3* -2)= OxCl -6 therefore OxCl = +5
the answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.
The oxidation number of oxygen in OF2 is 2.
The oxidation number of oxygen when combined with fluorine is -1. Oxygen usually has an oxidation number of -2, but when combined with a more electronegative element like fluorine, oxygen's oxidation number becomes -1.

The oxidation number of oxygen is -2 in most of its compounds
The oxidation state of chlorine in the chlorate ion ClO3 is +5. This is because oxygen is more electronegative than chlorine and its oxidation state is typically -2 in compounds. Since there are three oxygen atoms with a total charge of -6 in the chlorate ion, the oxidation state of chlorine must be +5 to balance out the charge.
the answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.

The oxidation number of oxygen when combined with fluorine is -1. Oxygen usually has an oxidation number of -2, but when combined with a more electronegative element like fluorine, oxygen's oxidation number becomes -1.
Usually the oxidation no of oxygen is -2 and the oxidation no of hydrogen is +1 in a compound.
The oxidation number of oxygen in OF2 is +2. Oxygen usually has an oxidation number of -2, but in this case, since there are two fluorine atoms each with an oxidation number of -1, the oxidation number of oxygen must be +2 to balance the overall charge.
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
the most common oxidation number for oxygen is -2.
