How does the reactivity change down Group 1 elements, and why?

The reactivity increases. Group 1 are the alkali metals so they react by losing their valence electrons. Caesium is more reactive because it gives up its electrons more readily. It has more inner shells so its valence electrons are further from the positive nucleus and feel less attraction.
