Scandium trifluoride exhibits the unusual property of negative thermal expansion, meaning it shrinks when heated. Hill and M. Sodupe and C.W. The scandium atom is in a trigonal bipyramidal environment, with O and N2 forming the apical sites [N2–Sc–O = 169.94(11)°]. , a mixture having the lowest melting point possible with those components). Scandium is a silvery-white metallic transition metal, often classified as a rare earth element (REE), together with yttrium (Y) and the 15 lanthanides (La). From a list of almost 2000 names and formulas, students will be given the opportunity to practice their ability to name ionic compounds, given the formula, and determine the formula given the name. Essential Role of Scandium Ion in Photocatalytic Oxygenation of Hexamethylbenzene. We report on the separation and recovery of scandium(III) from sulfate solutions using solvent extraction and a membrane transport system utilizing newly synthesized amic acid extractants. The electron configuration for scandium is: $$\ce{1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^1}$$ The $\ce{4s}$ and $\ce{3d}$ orbitals are relatively close in energy, so there are a few anomalies in the order of filling. Nilson named the element scandium after the Latin word ‘Scanda’ meaning Scandinavia, because the element occurs in rare minerals found there. 4Sc + 3O 2 → 2Sc 2 O 3. So reducing scandium(II) to scandium(I) will shift the orbital energies around to the very interesting result that one electron will occupy a 3d orbital while one will occupy the 4s orbital. Scandium aluminum alloys are a winning combination of scandium and aluminum metal. A. tin (II) B. tin (IV) C. scandium (IV) D. scandium (II) Scandium International Mining Corp. [SCY-TSX; SCYYF-OTC] said Thursday September 24 that it has filed a provisional patent application with the U.S. Patent Office for the use of various applications of scandium in lithium-ion batteries. This compound is made from Scandium and chlorine ions. Scandium was discovered by Lars Frederick Nilson (a Scandinavian) in 1876 in the minerals euxenite and gadolinite, which had not yet been found anywhere except in Scandinavia. By contrast, copper, [Ar] 3d 10 4s 1, forms two ions. Home » Chemistry » Scandium Iodate.
