Rare Earth Elements | Geology for Investors

Rare earth elements comprise the 15 lanthanides (yellow), yttrium (orange) and scandium (red). The term “rare earth element” is really a misnomer. Apart from the exceedingly scarce and radioactive promethium, most of the rare earth elements are relatively abundant in the earth’s crust. The reason for the name is that they are highly ...

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 nontrivalent rare earth ion stable in aqueous solutions, making it strongly acidic and moderately toxic, as well as a strong cerous state closely resembles the other trivalent rare earths.
