The rare-earth elements (REEs) are 15 elements that range in atomic number from 57 (lanthanum) to 71 (lutetium); they are commonly referred to as the “lanthanides.” Yttrium (atomic number 39) is also commonly regarded as an REE because it shares chemical and physical similarities and has affinities with the lanthanides.

Rare Earth Elements

Rare earth elements are a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides plus scandium and yttrium. Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties.

Rare earth elements (REEs) represent the group of 17 elements comprising 15 lanthanides, plus yttrium (Y) and scandium (Sc) (Table 1 ). Among the REEs, yttrium was discovered first in 1794 by a Finish chemist, Johan Gadolin who isolated an oxide and called it “yttria,” in a mineral collected from a quarry near the village of Ytterby in Sweden.

2022-9-23  The elements cerium through lutetium are called the lanthanides, but many scientists also, though incorrectly, call those elements rare earths. The rare earths are generally trivalent elements, but a few have other valences. Cerium, praseodymium, and terbium can be tetravalent; samarium, europium and ytterbium, on the other hand, can be divalent.
