In order to know if one element is more reactive than another, we must look at an activity series chart. A metal activity series is a ranking of relative reactivity of metals in displacement and other kinds of reactions that have been developed through studies. The most reactive elements are at the top of the activity series, and as you go down the chart the elements become less reactive.
