Multiple choice

Which of the following elements is the most nonmetallic?

  1. F

  2. Cl

  3. Br

  4. I
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nonmetallic character generally increases across a period and decreases down a group. F is in the same period as Cl, Br, and I, and it is the furthest to the right in the period, so it is the most nonmetallic.

Multiple choice
