The rare earths are the lanthanides — lutetium and all 14 elements between lanthanum and ytterbium across one row of the periodic table — plus scandium and yttrium, which tend to occur in the same ore deposits and have similar chemical properties to the lanthanides. These gray to silvery metals are often malleable with high melting and boiling poin...
Along some coasts, the night sea occasionally glows bluish green as bioluminescent plankton are jostled in the waves. Rare earth metals also radiate light when stimulated. The trick is to tickle their f-electrons, de Bettencourt-Dias says. Using an energy source like a laser or lamp, scientists and engineers can jolt one of a rare earth’s f-electro...
