| Cesium comes from the Latin word \"Caesius\" wich means \"sky blue\". It was dicovered in 1860 by Robert Wilhelm Bunsen and Gustav Robert Kirchoff while they were looking at samples of mineral water found in Durkheim, Germany. Cesium is a soft, silvery-gold alkali metal with a atomic number of 55. Its melting point is 28.5 degrees Celsius and its boiling point is 1,240 degrees Fahrenheit. It is reactive to water and moisture, and will explode if exposed to it. It will also burn if it comes in contact with air moisture. Cesium is one of the few elemental metals that is liquid at room temperature. Its symbol on the periodic table is Cs. Cesium is a naturally occurring element, however it is usually found in other minerals. Today, cesium is used in atomic clocks because it can cycle every second accurately when exposed to natural light. It also pulls trace gasses from vacuum tubes for scientists. | |
