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. Although REEs are not rare in …

Rare Earth Elements. Cerium is the most abundant of the rare earths. It is characterized chemically by having two valence states, the +3 cerous and +4 ceric states. The ceric state is the only non-trivalent rare earth ion stable in aqueous solutions, making it strongly acidic and moderately toxic, as well as a strong oxidizer.The cerous state closely resembles the …

The last naturally occurring rare earth element (lutetium) was discovered by 1907, but research into the chemistry of these elements was difficult, as no one knew how many real rare earth elements there were. Fortunately, 1913-14 solved the situation with the research of Danish physicist Niels Bohr and English physicist Henry Gwyn Jeffreys Moseley.
