Question
What is the correct order of increasing atomic radii for
the elements nitrogen (N), oxygen (O), fluorine (F), and carbon (C)?Solution
As we move across a period from left to right on the periodic table, the atomic radius decreases due to increasing nuclear charge. Therefore, Carbon (C) has the largest atomic radius, followed by Nitrogen (N), Oxygen (O), and Fluorine (F), which has the smallest atomic radius.
