It is 45th in order of abundance of all elements … 6s1 and the term symbol of caesium is 2S1/2. It is readily drawn into fine wires. It was discovered by Robert Bunsen and Gustav Kirchhoff in 1860 in Heidelberg, Germany, when they analyzed the spectrum of mineral water. Samples of cesium are kept in sealed containers, under an inert liquid or gas or in a vacuum. This element is a solid. Cesium is estimated to be present at an abundance of 1 to 3 parts per million in the Earth's crust, which is a fairly average abundance for a chemical element. Cesium (Cs), also spelled caesium, chemical element of Group 1 (also called Group Ia) of the periodic table, the alkali metal group, and the first element to be discovered spectroscopically (1860), by German scientists Robert Bunsen and Gustav Kirchhoff, who named it for the unique blue lines of its spectrum (Latin caesius, “sky-blue”). This refers to the color of the line in the spectrum the chemists saw that tipped them off about the new element. The symbol is constructed from a Symbol Identification Code, SIDC (sfgpewrh–mt in the image above), that provides i… Non-radioactive cesium is not a nutritional requirement for plants or animals, but it's not particularly toxic, either.
