Model Planetari Bohr Skandium (Sc)
Description
Fairly soft, silvery-white metal. Eighth most abundant 'rare earth' found in the earth's crust (5.0 ppm).
Uses
Scandium metal is used in some aerospace applications. Scandum oxide (Sc2O3) is used in the manufacture of high-intensity electric lamps. Scandium iodide (ScI3) is used in lamps that produce light having a color closely matching natural sunlight.
Sources
Occurs mainly in the minerals thortveitile (~34% scandium) and wiikite. Also in some tin and tungsten ores. Pure scandium is obtained as a by-product of uranium refining.
Pronounciation (English)
SKAN-di-em
