Praseodymium is a naturally occurring element, classified as a rare earth metal. It is found in various minerals, primarily in monazite and bastnäsite. While praseodymium can be synthesized in laboratories, it is predominantly obtained through mining and extraction from natural sources.
All of the praseodymium ordinarily found in nature is of a single stable isotope, 141Pr. Like all other elements, there are synthetic radioactive isotopes of praseodymium.
