Which of the two will be chemically more reactive? Element X with atomic number 16 or element Y with atomic number 17.

Explanation

To determine which of the two elements, X (atomic number 16) or Y (atomic number 17), is chemically more reactive, we need to analyze their electronic configurations and the implications for their reactivity.

### Step-by-Step Solution:

1. **Identify the Elements**:
- Element X has an atomic number of 16, which corresponds to sulfur (S).
- Element Y has an atomic number of 17, which corresponds to chlorine (Cl).
