E) chemical reactivity increases

Question

Quizplus · Accepted Answer

As you move down the alkali metal group from Li to Cs, the chemical reactivity increases due to the decrease in ionization energy and the increase in atomic size, which makes it easier for these elements to lose their outermost electron.
