The group includes the fifteen lanthanides, scandium, and yttrium. Scandium and yttrium are often considered rare earth elements because they tend to occur in the same ore deposits as the lanthanides and have similar chemical properties.
Despite their name, most rare earth elements are relatively abundant in the Earth's crust. However, due to
These applications include magnets for electric vehicles and wind turbines, catalysts for petroleum refining, phosphors for
