Historical Facts and Elements Uses:
Scandium, «skan dee uhm,» is a soft, silvery-white metal. Its chemical symbol is
Sc.  It has an atomic number of 21 and an atomic weight of 44.955910. In 1869, Dmitri Mendeleev of Russia predicted the existence of the element.  In 1879, Lars Nilson of Sweden discovered it in the minerals gadolinite and euxenite.  He named the element scandium after Scandinavia. Scandium is found in tiny amounts in over 800 minerals but is costly to extract and has no significant use.  Scandium melts at 1541° C and boils at 2831° C. It has a density of 2.989 grams per cubic centimeter at 20° C.
