Chemical element of periodic table. The oxide Sc2O3 and the hydroxide Sc(OH)3 are amphoteric:[24]. Diagram of the nuclear composition and electron configuration of an atom of scandium-45 (atomic number: 21), the most common isotope of this element. By processing 10 kg of euxenite and other residues of rare-earth minerals, Nilson was able to prepare about 2g of highly pure scandium oxide. Writing Quantum Numbers.

Scandium chemical element. It has the symbol Sc. [37] The first pound of 99% pure scandium metal was produced in 1960. [51] Lacrosse sticks are also made with scandium. [29][30][31][32], Dmitri Mendeleev, who is referred to as the father of the periodic table, predicted the existence of an element ekaboron, with an atomic mass between 40 and 48 in 1869. Scandium (Sc). Combined with mercury and iodine, scandium is used for producing bulbs. Scandium iodide (ScI3) is used in lamps that produce light having a color closely matching natural sunlight. Despite this fairly common occurrence, scandium rarely concentrates in nature. In part because of this similarity, scandium is often classified as a lanthanide-like element. Scandium is rather used for research since it is very rare and can be found only is a few rare types of minerals. 1.4.3 Number of Electrons. [55] One type of metal-halide lamp, similar to the mercury-vapor lamp, is made from scandium triiodide and sodium iodide. Il est classé avec l'yttrium et les lanthanides dans les terres rares. Rare Earth element. A silvery-white metallic d-block element, it was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. The soft, silver-white element is the first of the transition metals and is also assigned to the rare earth metals. Elemental scandium is considered non-toxic, though extensive animal testing of scandium compounds has not been done. Scandium (named for Scandinavia where Scandium ores can be found) has the symbol Sc and atomic number of 21, meaning the nucleus contains 21 protons.

Thus, the common elements in the range of scandium are atomic numbers 18 , 20 , 22 , and 24 ; with elements with odd atomic numbers 19 , 21 (scandium), and 23 being rarely produced, and thus much less common. Melting point of Scandium in Kelvin is 1814 K. State of Scandium is Solid at standard temperature and pressure Further research showed that this was an illusion caused by the relatively low temperature (below 3,500 K) of these stars masking the abundance signals, and that this phenomenon was observable in other red giants. Atomic Number of Scandium is 21. Flag of Sweden. As a metal, scandium has very low density, so it is used in alloys with other light metals like aluminum in aircraft industry, etc. [26], Compounds that feature scandium in oxidation states other than +3 are rare but well characterized. [43], Some items of sports equipment, which rely on high-performance materials, have been made with scandium-aluminium alloys, including baseball bats[50] and bicycle frames and components.
