WebAl ( Al 2 + Al 3 + + e −) requires more energy because the cation Al 2+ exerts a stronger pull on the electron than the neutral Al atom, so IE 1 (Al) < IE 3 (Al). The second ionization … WebThe ability of an atom to hold onto its valence electrons depends on the atomic size. The large atomic size of an atom will have the valence electron very far away from the … WebEnergy is always required to remove electrons from atoms or ions, so ionization processes are endothermic and IE values are always positive. For larger atoms, the most loosely bound electron is located farther from the nucleus and so is easier to remove. Thus, as size (atomic radius) increases, the ionization energy should decrease. tafelberg furnishers vacuum cleaners
