who discovered scandium

Why don't libraries smell like bookstores? Scandium was discovered by Larz F. Nilson in 1879. All Rights Reserved. He discovered scandium in 1879. Scandium iodide added to mercury vapor lamps produces a highly efficient light source resembling sunlight, which is important for indoor or night-time color TV. Scandium was named after where it was found, Scandinavia. One of its chief purposes is to combine with aluminum into an alloy used for high-performance equipment, especially by the aerospace industry. Lars Fredrik Nilson created 2 grams of high purity scandium oxide. Want to Know it? About 20 kg of scandium (as Sc2O3) are now being used yearly in the U.S. to produce high-intensity lights, and the radioactive isotope 46Sc is used as a tracing agent in refinery crackers for crude oil, etc. The name scandium came from the place it was discovered- Scandinavia. Group A vertical column in the periodic table. Sources and Uses . Sciences, Culinary Arts and Personal This limits the use of scandium because it takes excessive refining efforts to isolate a significant sample. 44.956 Glossary. Scandium: Despite being one of the most common elements on the planet, coming in 31st in abundance, it is not found in any major concentrations. Little is yet known about the toxicity of scandium; therefore it should be handled with care. The only natural occurence of scandium is the isotope Sc-45. Near pure scandium (99% pure) was not produced until 1960. The production of the first pound of 99% pure scandium metal was announced in 1960. Scandium can be obtained from the minerals thortveitite ((Sc, Y)2Si2O7), bazzite (Be3(Sc, Al)2Si6O18) and wiikite, but is usually obtained as a byproduct of refining uranium. It is a very light metal and has a much higher melting point than aluminum, making it of interest to designers of spacecraft. Industrial uses for scandium are limited, as there are no reliable, safe large-scale methods of producing large quantities of scandium. Scandium is the 50th most common element in the earth crust and 35thmost abundant element in the Sun. Discovered by. (L. Scandia, Scandinavia) On the basis of the Periodic System, Mendeleev predicted the existence of ekaboron, which would have an atomic weight between 40 of calcium and 48 of titanium. Lars Fredrik Nilson was the discoverer. Scandium is a silvery white, moderately soft metal. Period A horizontal row in the periodic table. Scandium is created when stars go supernova. Who discovered scandium? After Russian chemist Dmitry Ivanovich Mendeleyev in 1871 predicted this element’s existence, tentatively calling it ekaboron, Swedish chemist Lars Fredrik Nilson in 1879 discovered its oxide, scandia, in the rare-earth minerals gadolinite and euxenite, and Swedish chemist Per Teodor Cleve later in 1879 identified scandium as the hypothetical ekaboron. About 20 kilograms (44 pounds) of scandium oxide (Sc2O3), also known as scandia, are used each year in the United States in the production of high intensity lights. Say what? See the related link. Become a Study.com member to unlock this Scandium is not thought to be poisonous, but due to limited testing on live animals, it should be handled carefully in all of its compounds. Scandium, which has the the chemical symbol Sc, is a silvery-white metal. Instead, scandium is well distributed as a contributing element in a wide variety of minerals. Most scandium is presently being recovered from thortveitite or is extracted as a by-product from uranium mill tailings. Despite is prevalence in the crust, scandium is spread thinly throughout various minerals. Scandium is a soft, light metal that might have applications in the aerospace industry. It is expected that scandium-aluminum alloys will be important in the manufacture of fuel cells. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element, together with yttrium and the lanthanides.It was discovered in 1879 by spectral analysis of … his team. answer! This member of the transition elements group is a silver-white that has been historically categorized as a rare earth element.

Scandium tarnished in air and burn easily, once it has been ignited. Scientists have only studied a few compounds of scandium. When did organ music become associated with baseball? However, it is probably not a great idea to eat it! Scandium has other uses in a variety of compounds. Within those mines, scandium is actually a byproduct of the mining of other elements, with the end result being scandium oxide. Its existence was originally predicted by Dmitri Mendeleev ten years before. © copyright 2003-2020 Study.com. Tungsten wire and a pool of molten zinc served as the electrodes in a graphite crucible. This metallic element was not used commercially until 1970. Scandium is a silver-white metal which develops a slightly yellowish or pinkish cast upon exposure to air. Thortveitite (Scandium silicate) contain 45% scandium in the form of scandium oxide but it is very rare in nature. Earn Transferable Credit & Get your Degree. Estimated Crustal Abundance: 2.2×101 milligrams per kilogram, Estimated Oceanic Abundance: 6×10-7 milligrams per liter, Number of Stable Isotopes: 1 (View all isotope data). The table below shows the abundance of Scandium in Universe, Sun, Meteorites, Earth's Crust, Oceans and Human Body. Scandium was discovered in the minerals euxenite and gadolinite in Scandinavia. Despite being one of the most common elements on the planet, coming in 31st in abundance, it is not found in any major concentrations. How will understanding of attitudes and predisposition enhance teaching? What is the popular or general journal called in English? It is a very rare metal and has very limited availability. Metallic scandium was first prepared in 1937 by Fischer, Brunger, and Grienelaus who electrolyzed a eutectic melt of potassium, lithium, and scandium chlorides at 700 to 800oC. At room temperature, scandium is a solid metal. The element Scandium was discovered by Lars Fredrik Nilson in year 1879 in Sweden . Your email address will not be published. Services, Working Scholars® Bringing Tuition-Free College to the Community. Scandium is mostly produced as a by-product during the extraction of uranium through mineral davidite which contain around 0.02% scandium oxide. Scandium was discovered by Lars Fredrik Nilson, a Swedish chemist, in 1879 while attempting to produce a sample of pure ytterbia from 10 kilograms of the mineral euxenite ((Y, Ca, Er, La, Ce, U, … Create your account. Lars Fredrik Nilson was the discoverer. Metallic scandium was first produced in 1937 and the first pound (0.45 kilograms) of pure scandium was produced in 1960. All rights reserved. Within those mines, scandium is actually a byproduct of the mining of other elements, with the end result being scandium oxide. Only around 20 kg of scandium oxide is used each year in the US to make discharge lamps. Scandium is pronounced as SKAN-dee-em. Scandium (Sc) has an atomic number of twenty-one.
