Write the compounds of aluminium with the following elements
Oxygen , Sulphur, Nitrogen.

Explanation

To find the compounds of aluminum with the elements oxygen, sulfur, and nitrogen, we need to consider the oxidation states of aluminum and the respective elements. Here’s how to derive the compounds step by step:

### Step 1: Compounds of Aluminum with Oxygen
1. **Identify the oxidation states**:
- Aluminum (Al) typically has an oxidation state of +3 (Al³⁺).
- Oxygen (O) typically has an oxidation state of -2 (O²⁻).

2. **Cross-multiply the charges**:
