The oxidation number of nitorgen in nitric acid HNO3 is

O = -2

H = + 1

above should be known to you since these are among oxidation number rules :

to find the oxidation number of N , we need to use the rule ' that the sum of the oxidation number of the each element of a compound is equal to the o if the compound is neutral or the net charge of it if the compound has a net charge.So, in HNO3 lets say that the Nitrogen charge is x

1 + X + (-2) 3 = 0

1+ x+ (-6) = 0

x -5 = 0

X = +5

Nitrogen has +5 oxidation number


Nitrogen has +5 oxidation number in HNO3
