What is the hybridization of the nitrogen in the azide ion?
Here are the resonance structures we can draw for the azide anion. Resonance structure A has an octet on each nitrogen and just one unit of formal charge on each nitrogen Resonance structures B and C also have an octet around each nitrogen, but there is a rather large formal charge of -2 on one of the nitrogens.Web
