What is the coordination number of the metal atom if its! geometry is tetrahedral?

Explanation

To determine the coordination number of a metal atom with tetrahedral geometry, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Tetrahedral Geometry**:
- Tetrahedral geometry refers to a molecular shape where a central atom is surrounded by four other atoms (or ligands) positioned at the corners of a tetrahedron. The bond angles between the ligands are approximately 109.5 degrees.

2. **Identify the Number of Ligands**:
