Elemental Form| The alkali metal cesium, is silvery-white, soft and ductile. It has the lowest melting point of any alkali metal. Cesium reacts violently with water and due to its reaction with oxygen, should be stored in the absence of air. Located in the lower left-hand corner of the periodic table, cesium is the most electropositive element and has the lowest ionization potential. | ||||
