Difference between Rare Earth Element and Scandium

RARE EARTH ELEMENT vs SCANDIUM: NOUN

Any of a group of seventeen soft, lustrous, sometimes magnetic metals that form trivalent salts; they include the lanthanides plus yttrium, scandium, thorium and sometimes zirconium.
Any element of the lanthanide series (atomic numbers 57 through 71)

A metallic chemical element, atomic number 21, obtained from some uranium ores; it is a transition element.
A rare metallic element of the boron group, whose existence was predicted under the provisional name ekaboron by means of the periodic law, and subsequently discovered by spectrum analysis in certain rare Scandinavian minerals (euxenite and gadolinite). It has not yet been isolated. Symbol Sc. Atomic weight 44.
Chemical symbol, Sc; atomic weight, 44. An elementary body discovered by Nilson in 1879, by the help of the spectroscope, in the Scandinavian mineral euxenite.
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. : Periodic Table.
A white trivalent metallic element; sometimes classified in the rare earth group; occurs in the Scandinavian mineral thortveitite
