It is a silvery-white and relatively stable in air, rare earth metal. It can be prepared by the reduction of anhydrous LuCl 3 or LuF 3 by an alkali or alkaline earth metal. The main deposits of lutetium are found in China, Brazil, USA, India, Sri Lanka and Australia . The radioactive isotope is used to determine the age of meteorites relative to that of Earth. Applications. The name of Lutetium by the way has been derived from the Latin name of Paris being Lutetia as its discoverer Georges Urbain was a professor at the Sorbonne in Paris in 1907 at the time of its discovery. Georges Urbain, Charles James and Carl Auer von Welsbach independently discovered lutetium from ytterbium oxide. The most common source of commercially produced Lutetium is the mineral monazite. Common chemical compounds are also provided for many elements. He didn't believe that ytterbia was made of only one element. Lutetium is quite rare and its extraction is also very challenging.

The element lutetium was named after Lutetia, the Roman name for a small town which grew to become the modern city of Paris. How well do you know their symbols? Comprehensive data on the chemical element Lutetium is provided on this page; including scores of properties, element names in many languages, most known nuclides of Lutetium. Lutetium was discovered by scientists who were carrying out science experiments and scientific research. Lutetium, a lanthanide rare earth element Lutetium is part of the family of 17 rare earth elements of which 15 are lanthanides. The metal is silvery white and relatively stable in air. Amazingly, this metal was discovered by three separate scientists in the same year. Neuroendocrine tumours (NET) are positive tumours that originate in the neuroendocrine cells of organs, including in the gastrointestinal tract, the pancreas and the lungs. Even though the naming rights for the element went to Urbain it was later found that his sample only contained traces of the element and Welsbach’s sample was pure. Lutetium is not an abundant element. Lutetium-177 therapy is only used on men who suffer from cancer that has originated in the prostate and who have exhausted other previous lines of treatment. The name lutetium became widely accepted except in Germany, where it was commonly called cassiopeium until the 1950s. Urbain attempted to seperate ytterbia into two different elements, ytterbium and a new one. Lutetium is also found in the products of nuclear fission. It is considered to be a rare earth element and occurs at just 0.5mg/kg in the crust of the earth. We increase the value of your business. The element Lutetium was discovered by Georges Urbain in year 1907 in France and Germany . The metal is easily dissolved in diluted acids—except hydrofluoric acid (HF), in which a protective layer of LuF3 forms on the surface and prevents the metal from further dissolution. For example, C… Group: Lanthanides: Melting point: 1663°C, 3025°F, 1936 K: Period: 6: Boiling point: 3402°C, 6156°F, 3675 K: Block : f: Density (g cm−3) 9.84: Atomic number: 71: Relative atomic mass: 174.967: State at 20°C: Solid: Key isotopes: 175 Lu: Electron configuration [Xe] 4f 14 5d 1 6S 2: CAS number: 7439-94-3: ChemSpider … They all discovered the element as an impurity in ytterbium oxide, which was originally assumed to consist entirely of the element ytterbium! Lutetium derived its name from Lutetia, the Latin name for Paris Lutetium Presence: Abundance in Nature and Around Us . … The spelling of the element was changed from lutecium to lutetium in 1949. There is also ongoing debate over whether it is actually a lanthanoid. Lutetium is pronounced as loo-TEE-shee-em. It has proven itself to be an effective therapy for managing metastatic prostate cancer or cancer of the prostate after other types of treatment have failed. Answers to life's questions, Why are Whale Sharks an Endangered Species, How Many Countries Make up the Commonwealth. Lutetium. He showed great courage and compassion as a physician during this period, and some believe his POW … The worldwide production is just 10 tonnes a year and most lutetium is produced in China, the United States, Brazil, India, Sri Lanka and Australia. Natural lutetium consists of two isotopes: stable lutetium-175 (97.4 percent) and radioactive lutetium-176 (2.6 percent, 3.76 × 1010-year half-life). These elements were identical with "aldebaranium" and "cassiopeium", independently discovered by von Welsbach at about the same time. Our videos. ATOMIC NUMBER 71. It is not found free in nature and is present along with several rare minerals. Discovered by: George Urbain in 1907: Chemical Properties of Lutetium. Navigate parenthood with the help of the Raising Curious Learners podcast. The metal is prepared by metallothermic reduction of the anhydrous halides by alkali or alkaline-earth metals. The only commercially viable source of lutetium is monazite, which contains just 0.0001% of lutetium!

Lutetium was actually the last lanthanide to be isolated in 1907; and was simultaneously discovered by three chemists working in different parts of the world. Lutetium: history Lutetium was discovered by Georges Urbain and Carl Auer von Welsbach in 1907 at France, Germany. Lutetium was first discovered in the early 1900s by two chemists working independently. It is never found in free form in nature, but is found in small amounts as a part of certain minerals. Though lutetium composes only trace mounts (less than 0.1 percent by weight) of the commercially important minerals bastnasite and monazite, it has proved feasible to extract the metal as a by-product. It becomes superconducting at 0.022 K (−273.128 °C, or −459.63 °F) and pressures exceeding 45 kilobars.
