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.
This is a list of rare earth elements, which are metals. Both the tradition REEs and other elements classified as rare earth metals are listed.
But do you even know what rare earth elements are? According to the USGS, “The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. (Try naming all 17 before looking at the chart below.)
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]).
A precise definition of rare earth elements (REEs) and in-depth discussion of how common REEs are, worldwide REE production, and current REE production. Portal for information on annual production, price, and use of rare earth elements since 1997, plus links to further information.
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...
Statistics and information on the worldwide supply of, demand for, and flow of the mineral commodity group rare earths - scandium, yttrium, and the lanthanides. The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays.
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. Despite the name, these elements are fairly abundant in the Earth’s crust.
Heavy and light rare earth elements: The rare earth elements are often subdivided into "Heavy Rare Earths" and "Light Rare Earths." Lanthanum, cerium, praseodymium, neodymium, promethium, and samarium are the "light rare earths."
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.
