An Overview of Scandium (Sc or Element 21)

Scandium is the transition metal with the lowest atomic number. The discovery of scandium filled a spot predicted by Mendeleev's periodic table. Scandium took the place of the placeholder element eka-boron. Most scandium compounds have scandium with the Sc 3+ ion. Scandium has an abundance in the Earth's crust of 22 mg/kg (or parts per million).

Scandium Teach Nuclear

Metallic scandium was first prepared in 1937 by Fischer, Brunger, and Grienelaus who electrolyzed a eutectic melt of potassium, lithium, and scandium chlorides at 700 to 800 o C. Tungsten wire and a pool of molten zinc served as the electrodes in a graphite crucible. Pure scandium is now produced by reducing scandium fluoride with calcium metal.

Oxidation state Wikipedia

The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation of an atom in a chemical compound. Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were ionic, with no covalent component. This is never exactly true for real bonds. The term oxidation was
