Praseodymium is a soft, malleable, silvery-yellow metal. It belongs to the group of lanthanoids in the periodic table of the elements. It reacts slowly with oxygen: in the air it forms a green oxide that does not protect it from further oxidation. The other rare metals are more resistant to corrosion in the air, but still have to be stored under oil or coated with plastic. It reacts quickly with water.
