REMs are further broken down into heavy and light categories where heavy rare earth elements (HREE) are considered more valuable than light rare earth elements (LREE). Both types of lanthanides are non-radioactive, and they’re highly desired for many clean energy, engineering, and manufacturing ...

Yttrium(IT-ree-em), is arare earth element. This means that it has some unique properties that make it very important for use in modern technologies. There are only 17 rare earth elements in the periodic table of the elements. They have some similar chemical properties that allow us to mak...
could be alone in the universe. The first reason Earth was able to become this welcoming blue sphere is because it's at just the right distance from the Sun, in a narrow zone not too hot and not too cold, where the temperatures are compatible with liquid water and life....
an Earth Scientist will have been involved in getting the electricity and/or gas in your home and the petrol/diesel into your car, as well as finding the rare earth elements for your smart phone. Perhaps most crucially, it is Earth Scientists who work to understand where is safe for us ...

What are the three elements of GPS? GPS is made up of three different components, called segments, that work together to provide location information. The three segments of GPS are: Space (Satellites) — The satellites circling the Earth, transmitting signals to users on geographical position and...
2nd subgroup: rare earth elements, subdivided in the series of lanthanides and the series of actinides including La and Ac themselves (Rare earth metals). 3rd subgroup: a heterogenous group p-elements including the metal Bi, the amphoterous oxides forming elements Al, Ga, In, Tl, Sn, Pb,...

which dominates the market. Other sources include Australia and the U.S. They are preferred for their strength and ability to operate efficiently at high temperatures. Because of their unique chemical properties, other rare earth elements like lanthanum and cerium can be used in battery electrodes ...
