Chemical properties – Scandium symbol, electronic configuration, density


Scandium is a transition metal. It was discovered in 1879 by spectral analysis, of the minerals euxenite and gadolinite from Scandinavia. The main application of scandium by weight is in aluminium-scandium alloys for minor aerospace industry components. Some items of sports equipment, which rely on high performance materials, have been made with scandium-aluminium alloys. It is also used to make high-intensity discharge lamps.
