WebRare Metals and Metalloids (RMs) are physically and chemically dissimilar to rare earth elements. However the RMs are diverse and share few overarching similarities. The … The rare-earth elements (REE), also called the rare-earth metals or in context rare-earth oxides, and sometimes the lanthanides (although yttrium and scandium, which do not belong to this series, are usually included as rare earths), are a set of 17 nearly-indistinguishable lustrous silvery-white soft heavy metals. … Meer weergeven A table listing the 17 rare-earth elements, their atomic number and symbol, the etymology of their names, and their main uses (see also Applications of lanthanides) is provided here. Some of the rare-earth elements … Meer weergeven Rare-earth elements, except scandium, are heavier than iron and thus are produced by supernova nucleosynthesis or by the s-process in asymptotic giant branch stars. In nature, spontaneous fission of uranium-238 produces trace amounts of radioactive promethium, … Meer weergeven Until 1948, most of the world's rare earths were sourced from placer sand deposits in India and Brazil.
