Question

draw the electronic configuration of HNO3 and justify the + 5 oxidation number​

Answer 1

Explanation:

See the net charge on the compound is 0. Let the oxidation state of N be x. We know that the oxidation state of H is +1 because it is the most electropositive here and it shows -1 state only when the other elements are more electropositive. Now O has an oxidation state of -2 in 99% cases.

So we solve like this ,

Sum of all individual oxidation states = net oxidation state of the compound

So +1 + x - 6 =0

Giving x=5

Hope this helps
