The rare earths are a group of 17 metallic elements that occur in nature as nonmetallic compounds. Ironically, they're not at all rare: As a group, they are about as abundant as lead in Earth's crust. Rare earths earned their name to distinguish them from the alkaline earth elements (like beryllium, calcium and magnesium) that were found in the same deposits where rare earths were first ...
