Lutetium (Lu)

Lutetium (Lu)

Lutetium ([Xe]4f145d16s2) (CAS 7439-94-3) is a lustrous, soft, ductile, silvery-white metal. It occurs in minimal amounts in most minerals containing yttrium. The pure metal has only been recently isolated and is one of the most difficult to prepare. Lutetium is relatively stable in air and reacts slowly with water.
