Question

Which of the following has the largest atomic radius?

• A. Chlorine
• B. Fluorine
• C. Iodine
• D. Oxygen

Answer 1

Answer:

C. Iodine

• Iodine has the largest atomic radius among the given elements because atomicradius increases down a group in the periodic table.

• The atomic radius generally increases down a group in the periodic table due to the addition of electron shells.

• This trend is because as you move down a group, each successive element has an additional electron shell, which increases the distance between the outermost electrons and the nucleus, resulting in a larger atomic radius.
