What is the covalency of nitrogen in `N_2O_5`?

Explanation

To determine the covalency of nitrogen in \( N_2O_5 \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of \( N_2O_5 \)**:
- The molecular structure of \( N_2O_5 \) consists of two nitrogen (N) atoms and five oxygen (O) atoms. The nitrogen atoms are bonded to oxygen atoms through a combination of single and double bonds.

2. **Draw the Lewis Structure**:
