Scandium is a kind of chemical element. The element symbol is Sc and the atomic number is 21. The elemental is a soft, silvery-white transition metal, often mixed with gadolinium and erbium, that is produced in small quantities and is about 0.0005% in the Earth's crust. Scandium is commonly used to make special glass, light and high temperature resistant alloys.
