Oxidation Number Worksheet
An oxidation number of an atom is a positive or negative number which shows how many electrons an atom has gained, lost, or shared to become stable.
Some of the features of Oxidation number are as follows:
1. It is the extent of charge of an atom which is developed in the formation of a compound.
2. It may be positive or negative for an element, E.g. Oxidation number of P in is -3 and +3, respectively.
3. It may be of different value in different compounds for the same element, E.g. Oxidation number of C in are -4, -2, 0, +2 and +4 respectively.
