[Properties]

  Samarium has a silver luster that is not significantly tarnished
under normal room conditions. It can be ignited in air at 150
degrees, however.
  Samarium is a rare earth that ranks fifth in abundance. It is
also a member of the lanthanide series of elements: lanthanum (La)
through lutetium (Lu).
  There are three allotropic forms known at the present time. The
alpha form exists up to 734 degrees and the beta to 922 degrees.
