What is the Lewis representation of the #"azide ion"#, #N_3^(-)#?

Answer 1

Well, if its #"azide ion"#, you got a negative charge.....

You gots #"azide ion"#, i.e. #:stackrel(-)N=stackrel(+)N=stackrel(-)N:#. This is the typical representation of the resonance structure, and thus the ion has a formal negative charge. Simple VESPER would insist, that the ion is LINEAR, i.e. #/_N-N-N=180^@#.

The Lewis representation of the azide ion, (N_3^-), consists of three nitrogen atoms bonded together in a linear arrangement with a single negative charge on the ion. Each nitrogen atom forms a single covalent bond with another nitrogen atom, and there is one lone pair of electrons on the central nitrogen atom.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
