As one of the periodic trends studied in this unit, reactivity of metals varies in a
predictable manner. Of the elements listed, which one is the most reactive metal and
why?
A:Rubidium because it has a large atomic radius, a low ionization energy, and a low
electronegativity
B:Barium because it has a small radius, high ionization energy, and high
electronegativity
C:Aluminum because it has a small atomic radius and a small number of protons
D:Lithium because it has a smaller radius than most other metals
