According to ……………..rule, nitrogen atom has ……………unpaired electrons

Explanation

To solve the question, we need to determine the number of unpaired electrons in a nitrogen atom and identify the rule that governs this arrangement. Here’s a step-by-step solution:

### Step 1: Identify the Atomic Number of Nitrogen
The atomic number of nitrogen (N) is 7. This means it has 7 electrons.

### Step 2: Write the Electronic Configuration
The electronic configuration of nitrogen can be written as:
- 1s² 2s² 2p³
