What is Neodymium?

Neodymium, with an atomic number of 60 and an atomic weight of 144.24. The element name is derived from Greek and the original meaning is "twin." In 1841, the Swedish chemist Mossander obtained a mixture of praseodymium and neodymium from cerium; in 1885, Weerspar, Austria separated the green praseodymium salt and the rose-colored neodymium salt, and determined that they were two new elements. The content of neodymium in the earth's crust is 0.00239%, which is mainly found in monazite and cericosite. There are seven isotopes of neodymium in nature: neodymium 142, 143, 144, 145, 146, 148, 150, of which neodymium 142 has the highest content.
