Which of the following elements would you expect to have the greatest first ionization energy?

Question

Quizplus · Accepted Answer

Br (Bromine) has the greatest first ionization energy among the options given because it is the closest to the noble gases in terms of its position on the periodic table. Elements closer to the noble gases (to the right and up on the periodic table) generally have higher ionization energies because they are closer to completing their valence electron shell, making them more stable and less willing to lose an electron.
