Why aluminium acts as a good reducing agent?

Explanation

### Step-by-Step Solution:

1. **Understanding Reducing Agents**: A reducing agent is a substance that donates electrons to another substance, causing the other substance to be reduced while itself gets oxidized.

2. **Aluminum's Electron Configuration**: Aluminum (Al) has the atomic number 13, which means it has three electrons in its outermost shell (3s² 3p¹). To achieve a stable electronic configuration (similar to that of noble gases), aluminum can lose these three electrons.

3. **Oxidation of Aluminum**: When aluminum loses three electrons, it gets oxidized to form aluminum ions (Al³⁺). The reaction can be represented as:
