Cesium (cs) chemical structure, technical & safety data, discovery, uses. Cesium (cs) is a metal with atomic number 55, group 1 and period 6 it can be non-radioactive or radioactive cesium-137 is one of its most common radioactive forms cesium-137 history cesium metal was first discovered in 1860 by two germans robert bunsen and gustav kirchhoff while working on flame spectroscopy. Cesium's symbol on the periodic table they discovered it in mineral water from a spa in germany, using a spectroscope — which they had discovered the previous year what are its uses is it dangerous cesium burns when it comes in contact with the air and vigorously explodes when exposed to water. What is cesium information and facts regarding the element cesium info about the element cesium includes the definition, classification, history, discovery, properties,use and occurrence. Spectrum analysis should become important for the discovery of hitherto unknown elements they proposed to give this new metal the name caesium from cæsius (latin), which the ancients used to designate the blue of the upper part of the firmament i shall name it cesium because of its beautiful blue spectral line. German chemists robert bunsen and gustav kirchhoff discovered cesium in 1860 when analyzing the spectrum of mineral water the name for the cesium is used in atomic clocks, photoelectric cells, as a catalyst to hydrogenate organic compounds, and as a 'getter' in vacuum tubes the isotope cs-137.
Symbol: cs date of discovery: 1860 name origin: latin caesius appearance: silver discoverer: fustov kirchoff obtained from: pollucite, lepidolite melting point: the most widespread use of cesium is in drilling fluids for the oil industry which mitigates the necessity of toxic suspended solids in drilling fluids cesium is. Cesium element facts data zone | discovery | facts | appearance & characteristics | uses | abundance & isotopes | references 55 cs 1329 the chemical element cesium is classed as an alkali metal it was discovered in 1860 by robert bunsen and gustav kirchhoff. Discovered in 1860, cesium was discovered by using the spectrophotometer to look at the lines identifying elements in durkheim mineral water spectral because cesium reacts readily with most kinds of gases, it is used as a getter (ie an absorber of unwanted gases) in electronic vacuum tubes and cathode-ray tubes. Cesium was discovered over 150 years ago, and since then there have been several uses for this chemical element in this lesson we will learn what.
Cesium reacts explosively with cold water, and reacts with ice at temperatures above –116 ºc cesium is fairly toxic uses: used as a catalyst promoter, as a cesium was the first element to be discovered using spectroscopic means by robert w bunsen and gustav r kirchhoff in 1860, the year after they invented the. Chemists such as robert bunsen and gustav kirchhoff who discovered cesium in 1860 when investigating the spectrum in mineral water uses of caesium caesium compounds are used as a drilling fluids in petroleum industry caesium compounds are commonly used to make special optical glass, manufacture.
However, because it is so reactive, it can seriously burn the skin, so it must be handled with great care only a few thousand kilograms of cesium are used each year a number of minerals contain significant amounts of cesium, including mica, beryl, feldspar, petalite, and pollucite, which is the mineral it is usually mined from. Cesium-137 ( 137 cs) january 2003 fact sheet 320-077 division of environmental health office of radiation protection who discovered cesium in 1860, r w bunsen and g r kirchoff discovered the element (the first to be discovered by the use of the spectroscope) and named it for the two bright blue lines.
Both were discovered in 1860-1861 by rw bunsen and gr kirchoff they were the first two elements to be discovered with a spectroscope rubidium is used almost exclusively for research, but cesium has some highly specialized industrial uses, including special glasses and radiation detection equipment. Cesium: cesium (cs), chemical element of group 1 (also called group ia) of the periodic table, the alkali metal group, and the first element to be discovered cesium reacts explosively with cold water it readily combines with oxygen, so it is used in vacuum tubes as a “getter” to clear out the traces of oxygen and other. The best-known uses are probably those involving a radioactive form of the salt caesium chloride with the non-radioactive caesium 133 occurs naturally, as a trace constituent in some minerals and in mineral water (which is where caesium was discovered) it is most concentrated in a mineral called. The first cesium metal was produced in 1881 because cesium is not mined domestically, the united states is completely dependent on imports historically, the most important use for cesium has been in research and development, primarily in chemical and electrical applications rubidium was discovered.
Discovery date, 1860 discovered by, gustav kirchhoff and robert bunsen origin of the name, the name comes from the latin 'caesius', meaning sky blue, and derived from its flame colour allotropes.
What is cesium a2 cesium (or caesium) is the most sublime and electropositive of all true elements it was discovered spectroscopically, in mineral water from durkheim germany by robert bunsen (of the existence of these lines has resulted in the experimental use of cesium in ir decoy flares used in aerial combat. The chemistry division's periodic table describes the history, properties, resources, uses, isotopes, forms, costs, and other information for each element history from the latin word caesius, sky blue cesium was discovered spectroscopically in 1860 by bunsen and kirchhoff in mineral water from durkheim. Its identification was based upon the bright blue lines in its spectrum and it was the first element discovered by spectrum analysis the first caesium metal was produced in 1882 by carl setterberg historically, the most important use for caesium has been in research and development, primarily in chemical and electrical. Caesium (cs) has an atomic number of fifty-five and fifty-five protons in the nucleus caesium was discovered by robert bunsen and gustav kirchhoff in 1860 its name, which is it is used to create drilling fluids for the petroleum industry, converting heat energy in the electrical production industry, and in nuclear reactors.
