The alkali metals are the most reactive, and their reactivity increases down the group. Cesium is the last alkali metal on the periodic table that can be obtained in quantities large enough to experiment with. It reacts explosively with water. Cesium is the most reactive alkali metal and therefore, the most reactive metal.
