Which of the following elements has the smallest atomic radius?

Which of the following elements has the smallest atomic radius?

Correct Answer: Fluorine

Step 1: Understand what atomic radius means. Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.
Step 2: Know that atomic radius generally decreases as you move from left to right across a period in the periodic table. This is because the number of protons increases, pulling the electrons closer to the nucleus.
Step 3: Identify the elements you are comparing. For example, if the elements are Fluorine, Oxygen, and Nitrogen, list them out.
Step 4: Look at the position of each element in the periodic table. Fluorine is to the right of both Oxygen and Nitrogen.
Step 5: Since Fluorine is further to the right, it has a smaller atomic radius compared to Oxygen and Nitrogen.
Step 6: Conclude that Fluorine has the smallest atomic radius among the given elements.
