This comprehensive guide delves into its physical and chemical properties, reactivity, abundance, and the cutting-edge uses in scientific research and technology. Learn about the safety measures and interesting facts surrounding this highly reactive element.
Caesium (IUPAC spelling; [9] also spelled cesium in American English) is a chemical element; it has symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F; 301.6 K), which makes it one of only five elemental metals that are liquid at or near room temperature .
Significance and Uses. Caesium is used in vacuum tubes as a “getter” to clean the traces of oxygen and other gases when sealed. Caesium compounds with chlorides are used in photoelectric cells. Caesium is used in industries as a catalyst promoter. Caesium nitrate is used to make optical glasses.
Photographs and descriptions of many samples of the element Cesium in the Periodic Table.
Cesium is an extremely reactive metal and the most alkaline of the elements. It reacts explosively upon contact with water producing cesium hydroxide (CsOH), an extremely strong base that can rapidly corrode glass. Uses of Cesium. Cesium is used in atomic clocks, which are incredibly accurate.
