![]() ![]() The final data column compares this percentage against the percentage of all minerals that contain the element listed in each row. A special application of cesium is that it is used in the manufacturing of most accurate atomic clock. Element: Cesium Symbol: Cs Atomic Mass: 132. Atomic number: 55: Relative atomic mass: 132.905: State at 20☌: Solid: Key isotopes: 133 Cs: Electron configuration Xe 6s 1: CAS number: : ChemSpider ID. ![]() The second data column lists this number as a percentage of all minerals listed with Caesium. Element: Chlorine Symbol: Cl Atomic Mass: 35.453 of Atoms: 1 Mass Percent: 21.058. The first data column contains the total number of minerals listed with Caesium and the element listed for that row. Using only the information provided in your question, one-twelfth the mass of an atom of C-12 is 1 unified atomic mass unit or 1 u, so the mass of a Cs atom. Atomic Number: 55 Symbol: Cs Atomic Weight: 132. The isotope Cs-137 is used in cancer treatments, to irradiate foods, and as a tracer for drilling fluids in the petroleum industry. A 'cesium(-beam) atomic clock' (or 'cesium-beam frequency standard') is a device that uses as a reference the exact frequency of the microwave spectral line emitted by atoms of the metallic element cesium, in particular its isotope of atomic weight 133 ('Cs-133'). Note that unlike other sections on this page this includes non-essential elements. Cesium is used in atomic clocks, photoelectric cells, as a catalyst to hydrogenate organic compounds, and as a getter in vacuum tubes. Atomic Structure of Cesium Atomic Radius: 3.34 Atomic Volume: 71.07cm3/mol Covalent Radius: 2.35 Cross Section (Thermal Neutron Capture)a/barns: 29. This table compares the known valid mineral species listed listed with Caesium and the other elements listed based on the official IMA formula. ![]() Minerals where Cs was previously thought to be a colouring agent probably contain other ions such as Mn#2+#.Ģ7 valid species containing essential CaesiumĬs + enters later phases in igneous rocks due to its large size.Ītom mole fraction relative to Si=1 (% uncertainty)Įlement association of Caesium in the Mineral World It is a very ductile, pale metal, which darkens in the presence of trace amounts of oxygen.
