Try Again Your answer is incorrect. • Left table: Your answer is incorrect. •Right table: Two of your answers are incorrect. Two sets of ionizations are shown in the tables below. Complete the tables by ordering each set of ionizations by increasing amount of energy required. In other words, for each set choose "1" next to the ionization that would require the least energy, "2" next to the ionization that would require the next least energy, and so on. ionization + Ne Ne + e + Cs → Cs + e + Rb Rb + e energy required 1 (least) î 2 3 (most) ↑ ionization + Ne Ne + e + Si Si te + Cs Cs + e X energy required 1 (least) 2 3 (most) S ↑ ↑ ↑
