In the 18th century when they were discovered, people understood rare to mean "new.". And "earths" was because before we understood electrons and atomic weight, we classified elements by their properties: gases, metals, non-metals, and earths. Lisa: In some ways they're actually the opposite of rare. They're everywhere.

Lutetium was the 16th of the rare earths to be identified. Using X-ray spectroscopy, Moseley demonstrated that only one rare earth element remained to be discovered: element 61. He determined the atomic numbers of the elements and showed that they were arranged in the periodic table in order of atomic number, not atomic …
