Going back to the Wikipedia article on scandium, this gives references to several organometallic examples in which scandium has reduced oxidation states, from +2 all the way down to 0. The metal itself was first prepared in 1938 by the electrolysis of potassium, lithium, and scandium chlorides in a eutectic mixture (i.e., a mixture having the lowest melting point possible with those components). Metals corrode under environmental conditions and slowly wear away like eroding iron. Before going over the complete list of metals, it is important that we define what is a metal. Among 25 (excluding nuclear isomers) radioactive isotopes with masses ranging from 36 to 61, the most stable is scandium-46 (half-life of 83.79 days), and the least stable is scandium-39 (half-life of less than 300 nanoseconds).
