![]() Robert Wilhelm Bunsen (1811-1899) invented many lecture-room and laboratory appliances, most famously the Bunsen burner. It was the first element discovered by spectrum analysis. Radium salts have been used as radiation sources in the treatment of cancer but are gradually being replaced in such therapy by cobalt and cesium.įacts about the History of the Discovery of Cesium ElementĬesium was discovered by Fustov Kirchoff and Robert Bunsen in 1860 from mineral water found in Dürkheim, Germany. Interesting information on the Medical Uses of Cesium, Health and Treatments. Medical Uses of Cesium - Health and Treatments What is Cesium? Occurrence of the Cesium ElementĬesium is found in the mineral pollux, or pollucite, which occurs on the island of Elba, in South Africa, in the United States in Maine and South Dakota, and in Manitoba, Canada.Ībundances of the element in different environments Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals. Alkali metals are soft, malleable, ductile, and are good conductors of heat and electricity. An Element classified as an Alkali Metal is a very reactive metal that does not occur freely in nature. Cesium is classified as an "Alkali Metal" and located in Group 1 elements of the Periodic Table. What is Cesium? Periodic Table Group and Classification of the Cesium ElementĮlements can be classified based on their physical states (States of Matter) e.g. The word Caesium originates from the Latin word 'caesius' which means "sky blue" from the bright blue lines in its spectrum. ![]() Long exposure can even cause coma or death.What is Cesium? Origin / Meaning of the name Cesium Due to this, nausea, vomiting, and bleeding may occur. Radioactivity: If a person comes in contact with a radioactive isotope of caesium then cell-damage may occur. Its advantages are that it has a half-life of 30 years and it has barium-137 as a stable end product. Nuclear application: Caesium-137 is used as a gamma emitter in industrial applications.Molecular Biology: High density caesium compound solutions such as caesium chloride, caesium sulfate, etc are used in density gradient ultracentrifugation.Atomic-clocks: They use the electromagnetic transition in the hyperfine structure of caesium-133 atoms as the reference point.It also helps bring rock cuttings to the surface and to maintain pressure on the formation during drilling of the well. The main function of drilling fluids is to lubricate drill bits. ![]() Petroleum exploration: The largest use of caesium is as a drilling fluid for extractive oil and petroleum industry. Relevance in Chemical and Related Industries This precipitated double salt is then decomposed and the water is evaporated to obtain pure caesium chloride. The grounded ore is dissolved in strong acids which leads to formation of caesium double salts. The caesium is extracted from pollucite mainly by acid digestion. The ore is crushed, hand-sorted, and then grounded. Caesium forms variety of compounds including variety of halides and oxides.įrom Pollucite: The mining and refining of pollucite is a selective process hence it is done on a smaller scale.Caesium can only be handled under inert atmosphere.It even reacts with ice whose temperature is as low as -116☌. It reacts explosively with water even at low temperatures. Caesium is pyrophyric in nature, which means that it spontaneously ignites in air. ![]() Among them, the only stable isotope is caesium-139.
