The rareearth elements (REE), also called the rareearth metals or (in context) rareearth oxides, or the lanthanides (though yttrium and scandium are usually included as rareearths) are a set of 17 nearlyindistinguishable lustrous silverywhite soft heavy metals. Scandium and yttrium are considered rareearth elements because they tend to occur in the same ore deposits as .
