Explain the relationship between the number of valence electrons and the reactivity of a metal.

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!

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
