Who identified scandium?: The first chemist who realised that scandium existed was Dimitri Mendeleev who, in 1869, was the creator of the first periodic table. He realised that there had to be an element between calcium and titanium and he named this theoretic element, ekaboron.

Ten years later, in 1879, Lars Fredrick Nilson identified a new element from rock samples found in Norway. He called this element scandium since it seemed restricted to certain mineral deposits found in Scandinavia. It was another Swedish scientist, Per Teodor Cleve, who realised that ekaboron and scandium were one in the same.

Scandium proved very difficult to separate from its compounds. It was not until 1960 that a 99% pure sample was obtained by electrolysis.

About scandium: In fact, scandium is rare on Earth. The element can be found in certain areas of Scandinavia and Madagascar. There is more scandium detected in the sun and other stars than to be found in the Earth's crust! Scandium is never found as the free element because it is too reactive.
