What is the oxidation number of nitrogen in the nitrate ion no31 -?

In NO with oxygen having -2 as its oxidation number (one of the major rules of oxidation numbering) the nitrogen has to have +2 as its oxidation number. For NO_3 you have 3*-2=-6 oxidation from all the oxygens so your nitrogen is going to have a +6 oxidation number.
Beside this, what is the oxidation number of nitrogen in the nitrate ion?
+5
In this way, what are the oxidation numbers of the nitrogen and oxygen atoms in the nitrate ion no3 -)?
For example, in NO3– the nitrogen is assigned an oxidation number of +5 and each oxygen an oxidation number of –2.
Since the Molecule NO3 is nonexistent as such, one of the O atoms must either be a peroxide or have an unpaired electron and an oxidation number of -1 instead of -2. Since N has 5 valence electrons [2s2, 2p3] its maximum positive ox number is +5. Consider nitric acid, HNO3 or nitrate ion NO3-.
