Rare Earths
Rare Earths. The rare earth metals are a family of 17 elements consisting of scandium, yttrium, and the lanthanum-group elements. The term "rare earths" is a misnomer, as some of these elements are not particularly rare and all of them are metals, not earths. The elements are similar in their chemical properties to aluminum.

Physical and Chemical Properties of the Rare Earths
Scandium, on the other hand, has a much smaller atomic radius, and the trivalent ionic size is much smaller than that of the heavy rare earths. Therefore, scandium does not occur in rare earth minerals, and in general has a chemical behavior that is significantly different from the other rare earth elements (Gupta and Krishnamurthy 2005).
