Rare earth elements facts. Rare earth elements (REE) are a group of 17 elements, including the 15 elements of the lanthanide series on the periodic table of elements together with the transition metals scandium and yttrium. The latter two elements exhibit similar properties to the lanthanides and are found in the same ore bodies.
1. What are rare earth elements? Strictly speaking, they are elements like others on the periodic table – such as carbon, hydrogen and oxygen – with atomic …
The estimated average concentration of the rare earth elements in the Earth's crust, which ranges from around 150 to 220 parts per million (table 1), exceeds that of many other metals that are mined on an industrial scale, such as copper (55 parts per million) and zinc (70 parts per million).
rare earth metal, Any of a large class of chemical elements including scandium (atomic number 21), yttrium (39), and the 15 elements from 57 (lanthanum) to 71 (see lanthanides). The rare earths themselves are pure or mixed oxides of these metals, originally thought to be quite scarce; however, cerium, the most plentiful, is three times as abundant as lead …

The name "rare earth" is defined in connection with the fact that they are, first, relatively rare in the crust (the content of (1.6-1.7) x 10-2% by weight) and, secondly, to form a refractory substantially water-insoluble oxides (oxides of these at the beginning of the XIX century and formerly known as "lands").
