Oxidation number of
Concept Introduction:
Oxidation number is integer value allotted to every element. It is formal charge occupied by atom if all of its bonds are dissociated heterolytically. Below mentioned are rules to assign oxidation numbers to various elements.
1. Elements present in their free state have zero oxidation number.
2. Oxidation number of hydrogen is generally
3. Oxidation number of oxygen is
4. Metals have positive oxidation numbers.
5. Negative oxidation numbers are assigned to most electronegative element in covalent compounds.
6. Sum of oxidation numbers of different elements in neutral atom is zero.
7. Sum of oxidation numbers of various elements in polyatomic ion is equal to charge present on ion.
