What is the oxidation number of in ?
Oxidation number: Oxidation number denotes the oxidation state of an element in a compound ascertained according to a set of rules formulated on the basis that electron pair in a covalent bond belongs entirely to a more electronegative element.
Calculating the oxidation number of Nitrogen(N) in :
The oxidation state of Oxygen(O) = -2
Consider the oxidation state of nitrogen(N) = x
Hence, the oxidation number of in is .
