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.

Uncommon. Uncommon monsters are the most easily breedable hybrid monsters in Monster Legends, having an average chance of 70% in a direct breeding. Their maximum level is 60 and their maximum 5-star ranked level is 90.
Rare earth metals, hard-to-find materials, with unfamiliar names such as lanthanum, neodymium and europium, are used in wind and solar energy projects, but dwindling supplies could hinder a roll-out of low carbon technologies and slow China's shift away from coal power. These compounds, which are highly toxic when mined and processed, also take a heavy environmental toll …

Rare Earth Ore Classification. Classification of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classification that follows analogous categories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host, or are related to, REE ores are carbonatite and phoscorite, igneous rocks composed principally of ...
The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's

The term "Rare Earth" originates from Rare Earth: Why Complex Life Is Uncommon in the Universe (2000), a book by Peter Ward, a geologist and paleontologist, and Donald E. Brownlee, an astronomer and astrobiologist, both faculty members at the University of Washington.
n November 12, 2002, Dr. John Chambers of the NASA Ames - search Center gave a seminar to the Astrobiology Group at the OUniversity of Washington. The audience of about 100 listened with rapt attention as Chambers described results from a computer study of how planetary systems form. The goal of his research was to answer a dec- tively simple question: How often would newly forming …

Discovery and history. Although the rare earths have been around since the formation of Earth, their existence did not come to light until the late 18th century.In 1787 the Swedish army lieutenant Carl Axel Arrhenius discovered a unique black mineral in a small quarry in Ytterby (a small town near Stockholm). That mineral was a mixture of rare earths, and the first individual element to be ...
Although they are called rare, these elements aren't so uncommon on Earth. According to the USGS, the elements, while initially considered rare, "are relatively abundant in the Earth's crust ...

4. Welwitschia. One of the longest living plants also known as the living fossil plant is again one of the rarest plant species found in Africa. This weird-looking plant has a woody, thick, short and stout trunk. This plant has a very slow growth rate and is believed to live for 1000 to 2000 years on earth. 5.
The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly-indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...

The rare earths are 17 metallic elements, located in the middle of the periodic table (atomic numbers 21, 39, and 57–71). These metals have unusual fluorescent, conductive, and magnetic properties—which make them very useful when alloyed, or mixed, in small quantities with more common metals such as iron. Geologically speaking, the rare ...
