What is the hybridization of nitrogen in the azide ion ?

Explanation

To determine the hybridization of nitrogen in the azide ion (N₃⁻), we can follow these steps:

### Step 1: Identify the Structure of the Azide Ion
The azide ion consists of three nitrogen atoms connected in a linear arrangement. The ion can be represented as N=N=N, with the overall charge of -1.

### Step 2: Count the Valence Electrons
Each nitrogen atom has 5 valence electrons (as it is in group 15 of the periodic table). For three nitrogen atoms, the total number of valence electrons is:
