Scandium is a chemical element with the symbol Sc and atomic number 21. It is a silvery-white metallic d-block element. Historically, it has been classified as a rare-earth element, [9] together with yttrium and the lanthanides. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. [10]

scandium (Sc), chemical element, a rare-earth metal of Group 3 of the periodic table. Scandium is a silvery white, moderately soft metal. It is fairly stable in air but will slowly change its colour from silvery white to a yellowish appearance because of formation of Sc 2 O 3 oxide on the surface.

Scandium is very widely distributed, and occurs in minute quantities in over 800 mineral species. It is the main component of the very rare and collectable mineral thortveitite, found in Scandinavia. Scandium can be recovered from thortveitite or extracted as a by-product from uranium mill tailings (sandy waste material).

Scandium is the 50 th most common element in the earth crust and 35 th most abundant element in the Sun. Scandium is found in ores of tin, uranium and tungsten. Thortveitite (Scandium silicate) contain 45% scandium in the form of scandium oxide but it is very rare in nature.
