If you go up the periodic table, the alkali metals get smaller, less reactive
smaller, more reactive
bigger, less reactive
bigger, more reactive

The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity. Period - reactivity increases as you go from the left to the right across a period. Group - reactivity decreases as you go down the group.

Explanation:

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
