Caesium ( Caesium is the IUPAC spelling) or cesium (Cesium is the American spelling) is a chemical element which has a chemical symbol Cs. The atomic number of cesium is 55. It is a silvery-gold soft, alkali metal that has a melting point of 83.3 °F ( 28.5 °C), that makes it one of only five elemental metals which are liquid near or at room temperature.
Cesium has chemical and physical properties same as of potassium and rubidium. It is highly reactive of all metals, it is pyrophoric and can react with water even at −177 °F( −116 °C). Cesium is the least electronegative element that has a value of 0.79 on the Pauling scale. Cesium has only one stable isotope which is cesium-133. It is mined largely from pollucite, while the radioisotopes, especially cesium-137, a fission product, are extracted from waste produced by nuclear reactors.
The Cesium was discovered by the German chemist Robert Bunsen and physicist Gustav Kirchhoff in 1860 by the method of flame spectroscopy. The very first small-scale applications for cesium were as a “getter” in photoelectric cells and in vacuum tubes.
