Mineral Species sorted by the element Sc Scandium (original) (raw)

Scandium (Sc) Element Properties

Atomic Mass 44.95591
Atomic Number 21
Name Origins From the Latin, Scandia, meaning "Scandinavia."
Year Discovered 1879
Discovery Credits Discovered by L. F. Nilson at Uppsala, Sweden.
Remarks Soft, silvery-white metal. Tarnishes in air and burns easily. Reacts with water to form hydrogen gas. Forms salts with acids. Little used.Diagnostic tests: There are no simple diagnostic tests to identify scandium. X-ray fluorescence spectroscopy is commonly employed to identify and analyze members of the group 3 elements.
