Praseodymium is a soft malleable, silvery-yellow metal. it's a member of the lanthanide group of the table of elements. It reacts slowly with oxygen: when exposed to air it forms a green oxide that doesn't protect it from further oxidation. It's more immune to corrosion in the air than the opposite rare metals, but it still must be stored under oil or coated with plastic. It reacts rapidly with water.
