How long will the footprints on the moon last? Rare minerals from Scandinavia and Madagascar are the only known concentrated sources of scandium. Scandium was discovered in 1879 by Lars Fredrik Nilson, who named it after Scandinavia. This limits the use of scandium because it takes excessive refining efforts to isolate a significant sample. 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. Lars Fredrik Nilson was the discoverer. Tungsten wire and a pool of molten zinc served as the electrodes in a graphite crucible. 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. The name scandium came from the place it was discovered- Scandinavia. When did organ music become associated with baseball? Group A vertical column in the periodic table. With a cost of $270 per gram ($122,500 per pound), scandium is too expensive for widespread use. Despite the discovery, 99.9% pure scandium wasn't isolated until 1960.

Little is yet known about the toxicity of scandium; therefore it should be handled with care. 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. However, it is probably not a great idea to eat it! from rare earth mixtures from euxenite and gadolinite, and is named for Scandinavia.

How will understanding of attitudes and predisposition enhance teaching? Within those mines, scandium is actually a byproduct of the mining of other elements, with the end result being scandium oxide. Only three mines currently extract scandium from ore. Later scientists pointed out that Nilson's scandium was identical with Mendeleev's ekaboron. The only natural occurence of scandium is the isotope Sc-45. Say what? 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, Th)(Nb, Ta, Ti)2O6).
