Lutetium appears as a silvery white form, also one of the hardest metals among the lanthanides. Lutetium is placed in the … When it is kept in moist air, the element loses its ability to resist corrosion. Lutetium is placed in the lanthanide series as the final element.Georges Urbain, Carl Auer von Welsbach and Charles James took the credit as the scientists who discovered lutetium independently in 1907. This radioactive isotope accounts for 2.5 percent. Lutetium was discovered independently by Georges Urbain (French chemist) and Carl Auer von Welsbach (Australian scientist) and Charles James (American chemist) in 1907. At room temperature, this silver-white metal is solid and dense. Most salts of lutetium are soluble in water and produce white crystals when the solution is dried. The isotope lutetium-176 has an abundance of 2.5% and is a radioactive isotope. It cautions, however, that while lutetium, like other rare-earth metals, is thought to have a low toxicity rating, it should be handled with care until more information is available.As mentioned, REEs rarely exist in pure form; they are usually concentrated in more than one mineral, and each mineral requires a different costly extraction technology and mineral processing. Lutetium reacts with water and forms lutetium hydroxide. It is not found free in nature and is present along with several rare minerals. Three separate scientists discovered lutetium in 1907, independent of each other.Charles James, Georges Urbain, and Carl Auer von Welsbach each extracted lutetium from a sample of the mineral ytterbia.After dispute between the three scientists, Urbain was allowed to name the element because his results were published first.Lutetium atoms are the smallest of any of the lanthanides.The contraction which causes that small size also causes lutetium to have the highest melting point, the highest density, and the highest hardness of all lanthanides.There are two naturally occurring isotopes of lutetium.Only one of those isotopes, lutetium-175, is stable, making it a monoisotopic element.The unstable isotope, lutetium-176, has a half-life of almost 38 trillion years.Only 2.5% of the lutetium found on Earth is in the unstable form.There are an additional 32 synthetic readioactive isotopes of lutetium.Lutetium is never found on Earth in a pure state, but is always found in a mineral with other elements.Lutetium is only available in the Earth's crust at about 0.5 milligrams per kilogram.The entire global production of lutetium is only around ten tons each year.Lutetium is one of the most expensive rare earth metals, costing approximately $10,000US per kilogram.The most abundant commercial mineral that contains lutetium is monazite, which is about 0.0001% of the lutetium.Because it is so expensive and so difficult to extract, there are very few commercial uses for lutetium.Lutetium's stable isotope is used in the petroleum industry as a catalyst.The lutetium-aluminium-garnet has been researched for possible uses in highly specialized lithography.Stable lutetium is also used with other agents as a detecting reactant in medical PET tests.The unstable isotopes of lutetium have more scientific applications, such as dating meteorites and as a radionuclide treatment for certain tumors. . 9 Fast Facts About Lutetium: An Infographic By Chris Calam 07.23.2019 According to the USGS , “The REE (Rare Earth Element) group is composed of 15 elements that range in atomic number from 57 (lanthanum) to 71 (lutetium) on the periodic table of elements, and are officially referred to as the ‘lanthanoids,’ although they are commonly referred to as the ‘lanthanides.’” The silver white metal is rare on earth. Lutetium is a large element, with an atomic number of 71 and an atomic mass of 174.976 AMU. Therefore, the people have to keep it in dry air. However, its salts, especially water-soluble compounds, are toxic. Its compounds are used as hosts for scintillators and X-ray phosphors, and the oxide is used in optical lenses. The atom of this element is the smallest one of all lanthanide atoms.Of all members of lanthanide element, lutetium has the highest hardness, melting point and density.As I have stated before, lutetium is included in list of rare elements on earth. Metallic…,Quicksilver with symbol Hg or in other words mercury will be…,Why don’t you read Facts about Matter in Chemistry to know…,In the nature, manganese is not available as a free element.…,Let me tell you the important Facts about Magnesium. The element number 71 is lutetium. For a kilogram of lutetium, you have to pay US$10,000.Even though lutetium has low level of toxicity, the compound should be handled with care. Its pure metal form was manufactured in 1953 [1]. Welsbach was recognized as Austrian mineralogist.The mineral ytterbia was the source of lutetium discovered by the three researchers. The symbol of lutetium is Lu.Lutetium is not an abundant element. It has the chemical symbol Lu. It is not found free in nature and is present along with several rare minerals. Lutetium metal is corrosion resistance and acts stable in air. Do you like chemistry? James was a chemist from United States. Group Lanthanides Melting point 1663 C, 3025 F, 1936 K Period 6 The synthetic rare earth promethium was produced later in the laboratory from uranium fission products.Lutetium was independently discovered by Carl Auer von Welsbach, Charles James, and Georges Urbain.The discovery echoed other rare earth discoveries in which a new element was discovered in minerals that had already been analyzed. At first, it was believed that ytterbium was the only element in the mineral.Lutetium is not widely used. It may cause skin irritation and explosion when heated.What do you think about 10 interesting facts about mica the…,10 Facts about Metallic Bonds will give you interesting information. Lutetium is quite rare and its extraction is also very challenging. Facts about Lutetium in one big list. Click for more facts & information. Its names were finalized as lutetium by Geroge Urbain in 1907. Lutetium can also be . Lutetium (Lu) has an atomic number of seventy-one.
