Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic transition metal‚ it has historically been sometimes classified as a rare earth element‚ together with yttrium and the lanthanoids. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. Scandium is present in most of the deposits of rare earth and uranium compounds‚ but it is extracted from these ores in only a few mines worldwide. Because of the low availability
