a rare, silvery-white, metallic chemical element occurring with various rare-earth elements, used to produce high-intensity light sources, etc.: symbol, Sc; at. no. 21
Origin of scandiumModL: so named (1879) by L. F. Nilson (1840-99), Swedish chemist ; from Medieval Latin Scandia, Scandinavia (source of the ore from which it was isolated) + -ium
A soft, silvery-white metallic element that is found in various rare minerals and separated as a byproduct in the processing of certain uranium ores, and that is used in materials for high-efficiency lighting. An artificially produced radioactive isotope is used as a tracer in studies of oil wells and pipelines. Atomic number 21; atomic weight 44.956; melting point 1,541°C; boiling point 2,836°C; specific gravity 2.989 (25°C); valence 3. See Periodic Table.
