Answer:
Neodymium is a naturally occurring element that was first discovered by Austrian chemist Carl Auer von Welsbach in 1885. It was discovered in the mineral cerite, which was found in a mine in the village of Bastnäs, Sweden. Neodymium can also be produced by nuclear reactors or particle accelerators by the process of neutron capture. This isotope of neodymium is highly radioactive and has a very short half-life, making it unsuitable for most practical applications.
