Cesium (US), or caesium, is a chemical element.
Discovery
editTwo German scientists (Gustav Kirchhoff and Robert Bunsen), in 1860, discovered Cesium in samples of mineral water in Bad Dürkheim, a spa town in Germany. Because of two blue lines from its emission spectrum, they chose the name, caesius, which is Latin for "sky blue".
