From the electronic configurations N (2,5), O (2,6) and F (2,7), answer the following questions:
Which one has the largest atomic radius?

Explanation

To determine which element among nitrogen (N), oxygen (O), and fluorine (F) has the largest atomic radius, we can follow these steps:

### Step 1: Understand the Position in the Periodic Table
- Nitrogen (N) is located in Group 15 and Period 2.
- Oxygen (O) is located in Group 16 and Period 2.
- Fluorine (F) is located in Group 17 and Period 2.

### Step 2: Analyze the Trend of Atomic Radius
