What is geometry of `ClO_2^(ɵ),ClO_3^(ɵ)` and `ClO_4^(ɵ)` ions?

Explanation

To determine the geometry of the ions \( \text{ClO}_2^- \), \( \text{ClO}_3^- \), and \( \text{ClO}_4^- \), we will follow these steps:

### Step 1: Determine the total number of valence electrons for each ion.

1. **For \( \text{ClO}_2^- \)**:
- Chlorine (Cl) has 7 valence electrons.
- Each Oxygen (O) has 6 valence electrons, and there are 2 Oxygens: \( 6 \times 2 = 12 \).
- The charge of -1 adds 1 electron.
