The valence electrons on atoms determine an element's reactivity. The more easily an element can attain a noble-gas electron configuration by losing or gaining a small number of electrons in its valence shell, the more reactive the element tends to be.

Got this from a quizlet I used a couple days ago, hope it helps!
