Astatine (At) may be rarest naturally occurring element in the Earth's crust, but it is a member of the halogen family (F, Cl, Br, I, At) and is presumed to have characteristics similar to other Group 17 elements. The meaning of the word "rare" in the term "rare earth elements" does not relate to the scarcity of these elements.
Neodymium is a chemical element with the symbol Nd and atomic number 60. Neodymium belongs to the lanthanide series and is a rare-earth element.It is a hard, slightly malleable silvery metal that quickly tarnishes in air and moisture. When oxidized, neodymium reacts quickly to produce pink, purple/blue and yellow compounds in the +2, +3 and +4 oxidation states.
Nov 18, 2013· A shortage of "rare earth" metals, used in everything from electric car batteries to solar panels to wind turbines, is hampering the growth of renewable energy technologies. Researchers are now working to find alternatives to these critical elements or better ways to recycle them.
Rare-earth element cerium is actually the 25th most abundant element in Earth's crust, having 68 parts per million (about as common as copper).Only the highly unstable and radioactive promethium "rare earth" is quite scarce.. The rare-earth elements are often found together. The longest-lived isotope of promethium has a half-life of 17.7 years, so the element exists in nature in only ...
