What are the coordination number of `Zn^(2+)` and `S^(2-)` ions in ZnS?

Explanation

To determine the coordination numbers of \( Zn^{2+} \) and \( S^{2-} \) ions in zinc sulfide (ZnS), we can follow these steps:

### Step 1: Understand the Structure of ZnS
Zinc sulfide (ZnS) crystallizes in a structure known as the zinc blende structure. In this structure, the arrangement of ions is crucial for determining their coordination numbers.

**Hint:** Research the crystal structure of ZnS to understand how the ions are arranged.

### Step 2: Identify the Positions of Ions
