The most reactive metals in the periodic tables are the alkali metals, followed by the alkaline earth metals. What is the most reactive metal family on the periodic table? Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium. The most reactive metal on the periodic table is francium.
