What are rare earths and why do they cluster near

"Rare earth" metals consist of Scandium, Yttrium, and 15 other metals of the so-called "Lanthanide" series toward the bottom of the Periodic Table of elements. Basically, these are the chemicals that we didn't study in chemistry class at school.. Like other metals, they have two electrons in the outer shell, but unlike "metallic" chemicals such as sodium or magnesium, they have a special ...
