The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.

5 days ago · Rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] through lutetium [Lu]).

The rare earth elements are all metals, and the group is often referred to as the "rare earth metals." These metals have many similar properties, and that often causes them to be found together in geologic deposits.

May 2, 2019 · The rare earth elements (REEs) or rare earth metals (REMs) are a group of metals found within the same ores and possessing similar chemical properties. Scientists and engineers disagree on exactly which element should be included in a list of the rare earths, but they generally include the fifteen lanthanide elements, plus scandium and yttrium.

The rare earth elements (REEs) are 17 metals in Group 3 of the Periodic Table comprising Lanthanide series elements and Scandium and Yttrium (due to similar physical properties and found in the same ores and deposits).

Dec 4, 2019 · Rare earth metals are actually not as rare as their name might imply. They are critical to high-performance optics and lasers, and essential to the most powerful magnets and …

5 days ago · The boiling points of the rare-earth metals vary by nearly a factor of three. Those of lanthanum, cerium, praseodymium, yttrium, and lutetium are among the highest of all the chemical elements, while those of europium and ytterbium can be placed in the group of metals with the lowest boiling points.

Rare earth elements (REEs), which comprise of only 17 elements from the entire periodic table, play a critical role to our national security, energy independence, environmental future, and economic growth.

Feb 15, 2025 · The rare earth elements are a group of transition metals, found mainly in the first row below the periodic table (the lanthanide series), plus scandium and yttrium.
