Praseodymium is a soft malleable metal that is a rare eath metal. Praseodymium was first discovered along with samarium and in a substance called didymium which was mistaken as a new element. Didymium was identified as a mixture of elements and in 1885 Carl Welsbach identified both Praseodymium and Neodymium as two elements. Praseodymium is used in the creation of permanent magnets and generators for hybrid cars and wind turbines. It is not found as a free element but in ores. It is a solid metal at room temperature with a melting point of 935°c and a boiling point of 3520°c.
