Ionization energy ________ as one goes down a group and ________ as one goes from left to right in a period.

Question

Quizplus · Accepted Answer

Ionization energy decreases as one goes down a group because the outermost electrons are farther away from the nucleus and experience a weaker attraction to the positively charged nucleus. Ionization energy increases as one goes from left to right in a period because the number of protons in the nucleus increases, which increases the attraction between the nucleus and the electrons, making it more difficult to remove an electron.
