What are the maximum and minimum oxidation numbers of N, S and Cl ?

Explanation

To determine the maximum and minimum oxidation numbers of Nitrogen (N), Sulfur (S), and Chlorine (Cl), we can analyze their electronic configurations and how they can gain or lose electrons to achieve stable configurations.

### Step-by-Step Solution:

1. **Determine the electronic configuration of each element:**
- **Nitrogen (N)**: Atomic number = 7
- Electronic configuration: 1s² 2s² 2p³
- **Sulfur (S)**: Atomic number = 16
