Rare Earth Elements Group

Rare Earth Elements Group. Though generally unfamiliar, the ree are essential for many hundreds of applications. All are metals and have many similar properties which often cause them to be found together in geologic deposits.

Rare earths, as the elements are called, were discovered beginning in the late 18th century as oxidized minerals—hence earths. the rarest rare earth is nearly 200 times more abundant than gold. Jump to navigation jump to search. Rare earth elements (rees) comprise a group of 17 elements with very similar chemical and physical properties, which include scandium (sc, z=21), yttrium (y, z=39), and the lanthanides with successive atomic numbers (z from 57 to 71).

Resource figures are current as at 31 december 2018.

The group consists of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium. The group of metals referred to as rare earth elements (ree) comprises the 15 elements of the lanthanide series. They are usually divided into the light ree (lree) and the heavy ree (hree); Rare earth elements or rare earth metals are one of 17 chemical elements within the periodic table.

According to the usgs, the rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides.

All are metals and have many similar properties which often cause them to be found together in geologic deposits.

Rare earth elements (ree) is the collective name for 17 chemically similar metallic elements (the lanthanides, scandium and yttrium) that occur in a wide range of ree bearing minerals and are mined collectively.

Rare earth elements or rare earth metals are one of 17 chemical elements within the periodic table.

Rare earth elements are a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides plus scandium and yttrium.

The rare earth elements, individually and as a whole group, are the quintessential symbol for the emerging, shifting global order, as china and the united.

The thirty rare earth elements are composed of the lanthanide and actinide series.
