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 .
Molar mass: 325.819 g·mol −1 Appearance white powder Density: ... Caesium carbonate or cesium carbonate is a chemical compound with the chemical formula Cs 2 C O 3.
Caesium-134 is not produced via beta decay of other fission product nuclides of mass 134 since beta decay stops at stable 134 Xe. It is also not produced by nuclear weapons because 133 Cs is created by beta decay of original fission products only long after the nuclear explosion is over. The combined yield of 133 Cs and 134 Cs is given as 6. ...
Caesium fluoride (cesium fluoride in American English) is an inorganic compound with the formula CsF. A hygroscopic white salt, caesium fluoride is used in the synthesis of organic compounds as a source of the fluoride anion. [ 5 ]
Caesium chloride or cesium chloride is the inorganic compound with the formula Cs Cl. This colorless salt is an important source of caesium ions in a variety of niche applications. Its crystal structure forms a major structural type where each caesium ion is coordinated by 8 chloride ions. Caesium chloride dissolves in water.
The molecular mass (m) is the mass of a given molecule. Units of daltons (Da) are often used. [1]
Caesium iodide or cesium iodide (chemical formula CsI) is the ionic compound of caesium and iodine. It is often used as the input phosphor of an X-ray image intensifier tube found in fluoroscopy equipment. Caesium iodide photocathodes are highly efficient at extreme ultraviolet wavelengths. [7]
