Does the first ionization energy decrease
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).
