# Azides of heavy metals explode when struck sharply, and are used in detonation caps. What is the Lewis structure for the most stable azide ion, N_3^-? Include lone pairs.

Each of the three nitrogen centres bear formal charges.....

#### Explanation:

We gots $15 + 1$ valence electrons to distribute over 3 centres, i.e. 8 electron pairs.....

""^(-):ddotN=stackrel(+)N=ddotN:^(-)

And the 8 electron pairs are distributed, and VESPER would predict a linear anion. There is a formal NEGATIVE charge associated with the structure.
