# Covalent bond in NO3 [duplicate]

Can anyone explain how the bonding is formed in NO3 because I can't understand how N can satisfy electron hunger of 3 oxygen atom

• Resonance. Count the number of electrons on the oxygens and nitrogen in each of the resonance structures. – Apoorv Potnis Feb 7 '18 at 11:57
• Please, clarify: are you talking about $\ce{NO3-}$ anion or $\ce{NO3}$ neutral radical . – permeakra Feb 7 '18 at 12:22
• @permeakra While I agree to clear up ambiguity here, for the electronic structure and the "electron hunger" it shouldn't matter that much. – Martin - マーチン Feb 7 '18 at 13:18
