Praseodymium is a chemical element with symbol Pr and atomic number 59. Classified as a lanthanide, Praseodymium is a solid at room temperature. J.C. Slater, J Chem Phys, 1964, 41 (10), 3199-3205. DOI:10.1063/1.1725697.

What is Praseodymium. Praseodymium (pronunciation pra-see-oh-DIM-ee-em [2]), represented by the chemical symbol Pr [1], is a soft transition element [8] belonging to the family of rare earth metals [3, 4]. Naturally occurring Pr has a single stable isotope with mass number 141 [1, 3].

Praseodymium was discovered in 1841. It is strong paramagnetic in nature. It is widely used as an alloying agent with magnesium to make high strength metal. It is found in house equipment like color television, lamps and glasses.

Praseodymium (Pr) is a silvery, ductile & malleable metal element with atomic number 59 in the Periodic Table. Learn its uses, properties, electronic configuration, health effects & more.

Praseodymium is soft, silvery, malleable, and ductile. It is somewhat more resistant to corrosion in air than europium, lanthanum, cerium, or neodymium, but it does develop a green oxide coating that falls off when exposed to air. As with other rare-earth metals, it should be kept under a light mineral oil or sealed in plastic.

Praseodymium is a soft, malleable, ductile, silvery metal. Praseodymium is one of the lanthanide rare earth metals. It forms a flaky black oxide coating (Pr 6 O 11) in air. Unlike many metal oxide layers, this one does not protect the metal from further oxidation. The pale green sesquioxide, Pr 2 O 3, is not stable in air. (4)
