The mostreactivemetal on the periodic table isfrancium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal iscesium. Cesium reacts explosively with water, though it is predictedfranciumwould react eve...
