Which is more acidic: `SO_2,SeO_2`, and `TeO_2`?

Explanation

To determine which of the oxides \( SO_2 \), \( SeO_2 \), and \( TeO_2 \) is more acidic, we can analyze the trend in acidity based on the properties of the elements in Group 16 (the chalcogens).

### Step-by-Step Solution:

1. **Identify the Elements and Their Group**:
- The elements in question are sulfur (S), selenium (Se), and tellurium (Te). They belong to Group 16 of the periodic table.

2. **Understand the Trend in Metallic Character**:
