Question

Reactivity of the alkali metals is best described by: *

4 points
increases within the group as you descend down the periodic table
decreases within the group as you descend down the periodic table
depends upon the number of valence electrons that are being removed
increased, then decreases for elements with more valence electrons
none of the above

Answer 1

Increases within the group as you descend down the periodic table

Step-by-step 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.
