RARE EARTH ELEMENTS

The International Union of Pure and Applied Chemistry (IUPAC) defines rare earth elements (REE) or rare earth metals as a collection of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides (Note: Even though lanthanoid means 'like lanthanum' and as such should not include lanthanum it has become included through common usage.

Rare Earth Properties

These elements, plus lanthanum (element 57) and actinium (element 89), are known collectively as the rare earth elements or rare earth metals. Actually, they aren't particularly rare, but prior to 1945, long and tedious processes were required to purify the metals from their oxides.
