Question

Place the following in order of increasing IE₁. K Ca Rb A) Ca < K < Rb B) Rb < Ca < K C) Ca < Rb < K D) Rb < K < Ca E) K < Ca < Rb

Quizplus · Accepted Answer

Ionization energy generally increases across a period and decreases down a group. Rb is below K in the same group, so it has the lowest IE₁. Ca is to the right of K in the same period, so it has the highest IE₁. Thus, the order is Rb < K < Ca.
