5. Magnets are made of heavy metals such as manganese, iron, cobalt, nickel, niobium, bismuth, praseodymium, neodymium, gadolinium, and dysprosium.
6. All other cerium isotopes are inverse beta decay or electron capture to isotopes of lanthanum, while that of the heavier isotopes is beta decay to isotopes of praseodymium.
7. Praseodymium and terbium form non-stoichiometric oxides containing Ln IV, although more extreme reaction conditions can produce stoichiometric ( or near stoichiometric ) PrO 2 and TbO 2.
