Rare Earth Elements - Geological Society of London

What are the rare earth elements? The rare earth elements (REE) are a group of seventeen metallic elements - the fifteen lanthanides, with atomic numbers 57 (lanthanum, La) to 71 (lutetium, Lu), together with yttrium (Y, atomic number 39) and scandium (Sc, atomic number 21). All have similar chemical properties. The lower atomic weight elements

Fun Facts About Rare Earth Elements - Thermo Fisher Scientific

Rare earth elements (REEs) are natural elements with an atomic number from 57 to 71. Today, many hybrid cars on the road carry with them about 10 pounds of lanthanum. Nickel-lanthanum hydride batteries are about twice as efficient as the standard lead-acid car battery. Bastnasite (crystal) Photo courtesy of iRocks.

RARE EARTH ELEMENTS - periodni

The rare earth elements are often described as being a 'light-group rare earth element' (LREE) or 'heavy-group rare earth element' (HREE). The definition of a LREE and HREE is based on the electron configuration of each rare-earth element. The LREE are defined as lanthanum, atomic number 57 through gadolinium, atomic number 64.
