What is meant by chelate effect?

Explanation

### Step-by-Step Solution:

1. **Definition of Chelate Effect**: The chelate effect refers to the increased stability of coordination compounds that contain chelating ligands, which can form multiple bonds with a metal ion.

2. **Understanding Coordination Compounds**: Coordination compounds consist of a central metal atom or ion surrounded by molecules or ions called ligands. These ligands donate electron pairs to the metal to form coordinate bonds.

3. **Denticity of Ligands**: Ligands can have different denticities, which refers to the number of coordinate bonds they can form with the metal ion.
- **Monodentate Ligands**: These can form only one coordinate bond (e.g., NH3).
