![]() Ductile means capable of being drawn into thin wires. Please type any word or choose alphabet below. Cesium is a silvery-white, shiny metal that is very soft and ductile. The metal is extremely reactive and pyrophoric, reacting with water even at 116 ☌. Caesium is an alkali metal and has physical and chemical properties similar to those of rubidium and potassium. It is a soft, silvery-gold alkali metal with a melting point of 28 ☌, which makes it one of only five elemental metals that are liquid at or near room temperature. The metal is extremely reactive and pyrophoric, reacting with water even at 116 ☌.Ĭaesium or cesium is a chemical element with symbol Cs and atomic number 55. ![]() Compared with potassium and sodium, rubidium is relatively rare, with a crustal abundance of just 78 mg kg-1 (Fyfe 1999). Atomic number: 55 Atomic weight (mass): 132.9054 g.mol-1 Group number: 1 (Alkali metals) Period: 6 Color: Silvery-golden alkali metal Physical state: Liquid at or near room temperature Half-life: From 500(100) s to 2.3 million years Electronegativity according to Pauling: 0.79 Density: 1.9 g.cm-3 at 20C Melting point: 28.5 C (83. It is a soft, silvery-gold alkali metal with a melting point of 28 ☌, which makes it one of only five elemental metals that are liquid at or near room temperature. Rubidium-cesium-antimony coating is commonly applied to the photo-cathodes of photo-multiplier tubes, which are used in radiation detection devices, medical imaging equipment, and night-vision devices. ![]() Cesium Formate is used in the production of urethane products and Cesium Sulfate is added to catalysts for use in the production of sulfuric acid.Definition of Cesium -> Caesium or cesium is a chemical element with symbol Cs and atomic number 55. Cesium Carbonate is an important base used to synthesize various compounds in organic chemistry. Cesium chloride is used as a phase transfer catalyst in organic chemistry. Cesium graphite is used as a method of removing trace amounts of radioactive cesium from hot loops utilized in sodium-cooled reactors due to its relatively high heat. Cesium is an ideal catalyst for this photoelectric process.Ĭesium compounds are widely used today for many manufacturing processes. Visit ChemicalBook To find more Cesium iodide() information like chemical properties,Structure,melting point,boiling point,density,molecular formula,molecular weight, physical properties,toxicity information,customs codes. The electrons in cesium atoms are stimulated by direct sunlight, and in photoelectric cells, these electrons flow to create an electric current. Cesium, which is mined mostly from pollucite, has a total of 39 known isotopes.Ĭesium is used in photoelectric cells used to convert sunlight into electricity. Because of this, it is best to keep this compound. ![]() The resulting salt is caesium silicate, or caesium waterglass, which is water-soluble and similar in properties to common waterglass. It reacts with glass: 2 CsOH + CaSiO 3 Cs 2 SiO 3 + Ca (OH) 2. Cesium is a very rare element and two main sources for cesium-containing ore is Canada and Zimbabwe. Caesium hydroxide is a very reactive alkali. The most reactive of all metals, it is pyrophoric and reacts with. Atomic Number: 55 Period Number: 6 Group Number: 1Ĭesium (Caesium) is a soft and silvery-gold metal, which belongs to the alkali group. Caesium has physical and chemical properties similar to those of rubidium and potassium. ![]()
