Scandium Element information, properties and uses

Scandium is very much a late starter compared to many of the other elements, due to its relatively low occurrence and the difficulty in obtaining it from its ores. For example, it wasn't until the 1960s when the first pound, or 450 grams, of high purity scandium was obtained. Compounds of scandium find use in organic chemistry.

The philosophical significance of Mendeleev SpringerLink

Abstract. The philosophical significance of Dmitri Mendeleev’s successful predictions of the properties of gallium and scandium vis a vis the acceptance of the Periodic Table 1874–1886 has been debated recently. This author presents evidence that De Boisbaudran and Cleve both respectively predicted the possible existence of gallium and scandium, but on the basis of the old TRIAD methodology.
