Hi, I'm Caesium . Me and my Alkali Metal siblings may be softies, but mess around with us and we may just give you the explosion you'd never see coming. Keep us away from water chaos! Caesium or cesium is a chemical element with symbol Cs and atomic number 55. It is a soft, silvery-gold alkali metal with a melting point of 28 °C (82 °F), which makes it one of only five elemental metals that are liquid at or near room temperature.
