The rare earth elements (also known as the rare earth metals) in the periodic table include the 17 chemical elements: scandium (Sc), yttrium (Y), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), and lutetium (Lu).
Excluding scandium and yttrium, all 15 rare earth elements are lanthanides. The scandium and yttrium are rare earth elements because they exhibit similar chemical properties as lanthanides, and also they tend to occur in the same ore deposits.
