Rare Earth Elements
The rare earth metals naturally occur together in minerals. For example, monazite is a mixed rare earth phosphate. There is very little difference in the solubility and complex formation ability of the rare earth metals. Rare earth metals are found with non-metals in their third oxidation state (3+). There is very little tendency of these ...

Rare earths | Institute for Rare Earths and Metals
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.
