WebReview Question 11.5 Does the first ionization energy increase or decrease from top to bottom in the periodic table for the noble gas family? from top to bottom because the … WebIn general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. This pulls the electron cloud closer to the nucleus, strengthening the nuclear attraction to the outer-most electron, and is more difficult to remove (requires more energy).
