OTHER INFO.

  • Under normal conditions, it behaves in aqueous solution as expected for a trivalent actinide ion.
  • In 1954 researchers from the Nobel Institute of Physics in Stockholm produced fermium-250 by bombarding uranium-238 with oxygen-16 ions
  • The new element was produced by nuclear fission of 17 neutrons with uranium-238 (which then underwent eight beta decays). (2)
