Answer:

Increases within the group as you descend down the periodic table

Explanation:

Hello,

In this case, since the reactivity of alkali metals increases within the group as you descend down the periodic table due to the fact that it is easier for electrons to be given or taken away due to the atomic size, which increases as much as the period increases.

That is why potassium reacts more heavily with water than sodium.

Best regards.
