Question Analysis
This question assesses the student's ability to arrange elements in order of increasing atomic radius within a period.

Key Concept Explanation
Atomic radius decreases from left to right across a period due to the increasing nuclear charge. Therefore, the element on the far right will have the smallest atomic radius, and the element on the far left will have the largest atomic radius.

Step-by-step Solution
1. Identify the elements: Nitrogen (N), Oxygen (O), Fluorine (F).
2. Recall that these elements are in Period 2 of the periodic table.
3. Arrange the elements from left to right: N, O, F.
