Caesium (IUPAC spelling) (also spelled cesium in American English) is a chemical element with the symbol Cs and atomic number 55.

It is a soft, silvery-golden alkali metal with a melting point of 28.

C (8 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. DISCOUNT CODE NOT VALID FOR THIS ITEM.

When exposed to air, cesium will ignite spontaneously. WWI, WWII, Revolutionary War, Civil War Collectibles. Locate cesium pure in stock and ready to ship right now online. Cesium is the most reactive metal on earth.

About of these are Chloride, are Halide, and are Agrochemical Intermediates. A wide variety of cesium pure options are available to you, such as feature, supply type, and grade standard.

The very pure gas-free cesium needed as a “getter” for oxygen in vacuum tubes can be produced as needed by heating cesium azide (CsN 3) in a vacuum. Because cesium is strongly photoelectric (easily loses electrons when struck by light), it is used in photoelectric cells, photomultiplier tubes, scintillation counters, and spectrophotometers. Thoisoi- Chemical Experiments! For the first time on you can now observe cesium as it is. For starters, there are only three metallic elements that are not silver-coloured.

Two are well-known and fairly obvious - gold and copper. Apparently, the beautiful gold diminishes if the sample is extremely pure since tiny traces of captured oxygen give it the colour. A 1lb chunk of sodium metal is thrown in the school pond. 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.

The fact that cesium melts in your hand makes it one of the most fascinating element samples you can have: I never cease to wonder at the beauty of it. Obtaining pure cesium is difficult since cesium ores are frequently contaminated with rubidium, an element that is chemically similar to cesium. To obtain pure cesium , cesium and rubidium ores are crushed and heated with sodium metal to 650°C, forming an alloy that can then be separated with a process known as fractional distillation. Nonradioactive cesium and its compounds are used for infrared flares, to make specialty glasses, and in beer brewing. First, the ore is sorted by hand.

There are two methods used to prepare pure cesium. Calcium metal may be combined with fused cesium chloride or electric current may be passed through a molten cesium compound. In a sample of pure cesium , metallic atoms are joined together by metallic bonds that consists of mutual attraction between the sea of their valence electrons and the positive ions that are what is left of each atom after its valence electron goes away.

The purity figure below, , refers to the weight percent of cesium in cesium formate.

Pure cesium metal reacts violently with air and water resulting in an explosion-like reaction. The most important source of commercial cesium is a mineral known as pollucite, which usually contains about 5– cesium oxide (Cs2O). Well, you could think of displacing the cesium with a more reactive metal. Francium has a half life of about minutes, and is so r.
