Webster's Revised Unabridged Dictionary
    • n Scandium (Chem) 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.

    • n scandium 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.

In science:

Keeping in mind that PSN and PST contain scandium, niobium and tantalum oxygen complexes, one can conclude that coefficient of nonlinearity for PSN should be larger than that for PST.

Wittig J, Probst C, Schmidt F A and Gschneidner K A Jr 1979 Superconductivity in a new high-pressure phase of scandium Phys.
Assembling the puzzle of superconducting elements: A Review
The Berkeley cyclotron accelerated α -particles and deuterons to bombard scandium oxide and titanium oxide, respectively. 48V was then produced in the reactions 45Sc(α ,p) and 47Ti(2H,n).
Discovery of the Vanadium Isotopes
The activities were measured with a Lauritsen-type quartz fiber electroscope. “It is thus clear the bombardment of scandium with 11 MeV α -particles gives rise to 48V, this isotope having a half-life of 16.2±0.3 days.
Discovery of the Vanadium Isotopes
Ba, 136Ba, and 137Ba were discovered by Aston as reported in his 1932 article The Isotopic Constitution and Atomic Weights of Caesium, Strontium, Lithium, Rubidium, Barium, Scandium and Thallium .
