Rare earth elements: Mendeleev's bane, modern marvels
The REs are a family of 17 metallic elements formed by the group III (Sc, Y) and the lanthanide series (La–Lu). The name "rare earth" is misleading and does not represent a geological scarcity ( Fig. 1B) ( 71 ). The origin of this description lies in the occurrence of REs as a mixture of elements in minerals, generally at low concentration.
