- n. A silvery-white metallic element found in various rare minerals and separated as a byproduct in the processing of certain uranium ores. 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 1,540°C; boiling point 2,850°C; specific gravity 2.99; valence 3. See Table at element.
Century Dictionary and Cyclopedia
- n. 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. Its oxid is a white powder resembling magnesia; the metal itself has not yet been isolated. Scandium is interesting as being one of three elements (the others are gallium and germanium) the predicted existence of which by Mendelejeff has been confirmed.
- n. A metallic chemical element, atomic number 21, obtained from some uranium ores; it is a transition element.
GNU Webster's 1913
- n. (Chem.) A rare metallic element of the boron group, whose existence was predicted under the provisional name
ekaboronby means of the periodic law, and subsequently discovered by spectrum analysis in certain rare Scandinavian minerals ( euxeniteand gadolinite). It has not yet been isolated. Symbol Sc. Atomic weight 44.
- n. a white trivalent metallic element; sometimes classified in the rare earth group; occurs in the Scandinavian mineral thortveitite

- From Latin Scandia, Scandinavia. (American Heritage® Dictionary of the English Language, Fourth Edition)
“The name scandium was derived from the Latin word Scandia which means Scandinavia.”
“There is a mad quest among nations now to find new rare-earth reserves - elements such as scandium, yttrium and lanthanum, to list just a few.”
“I look forward to his discussion of scandium and yttrium.”
“The materials (including scandium, yttrium and a group of elements called the lanthanides) have specific chemical and physical properties that make them useful in improving the performance of computer hard drives and catalytic converters, mobile phones, hi-tech televisions, sunglasses and lasers.”
“Check out the 44 Mag S&W 629, lightweight, constructed with scandium allow, I think you will trade in that 357 before your mext trip.”
“Im minus 7% body fat now, bones replaced w/lightweight scandium alloy!”
“I believe S&W is the largest single user of scandium.”
“Rare earths is a generic term that includes minerals such as scandium, lanthanum and yttrium.”
“China controls up to 97% of world production of these elements — which include samarium, scandium and yttrium — and its export quotas for this year are nearly exhausted.”
“For our story, only the lanthanides are relevant, so let's focus on those, along with scandium and yttrium.”
