Answer 2

Answer:

An element's reactivity is its tendency to lose or gain electrons. ... This trend occurs because each element, as you move down, has more inner electrons that shield the one valence electron from the nuclear charge making it less attracted. The Alkaline Earth Metals (Group 2) are the next most reactive of the metals.
