Rare Earth Elements: Their Importance in Understanding

The rare earth elements (REEs) are commonly defined as lanthanum (La) and the 14 elements comprising the Lanthanide series. The REE's typically exhibit trivalent oxidation states; however, Europium may also occur as Eu 2+ and Cerium may occur as Ce 4+ . The REE's ionic radii decrease on progression from La to Lu, which results in a slight but predictable change in their chemical affinity.
