Scandium chemically resembles yttrium and the rare earth metals more than it resembles aluminium or titanium. Thus scandium is sometimes seen as the scandium oxide, (Sc2)(03), and as scandium chloride, Sc(Cl)3. See also Scandium compounds. Isotopes Edit

However, scandium is distributed sparsely and occurs in trace amounts in many minerals. Rare minerals from Scandinavia and Madagascar such as thortveitite, euxenite, and gadolinite are the only known concentrated sources of this element. Thortveitite can contain up to 45% of scandium in the form of scandium oxide.

In 1869, Mendeleev noticed that there was a gap in atomic weights between calcium (40) and titanium (48) and predicted there was an undiscovered element of intermediate atomic weight. He forecast that its oxide would be X 2 O 3. It was discovered as scandium in 1879, by Lars Frederik Nilson of the University of Uppsala, Sweden.

Scandium was discovered by Lars F. Nilson in 1879, in Uppsala, Sweden. Nilson was studying the rare earth elements, attempting to isolate ytterbium from the minerals euxenite and gadolinite.. Part of Nilson's method required the preparation of erbia (erbium oxide) from the minerals, which was then reacted to form erbium nitrate.

Virtually no pure scandium metal is sold in the world, most of the scandium that trades hands is either scandium oxide, or master alloys like this. A master alloy is a precisely formulated mixture of metals that is meant to be added to a pot of more common metal to form the desired final alloy. This one is aluminum with about 2% scandium added.
