Mendelevium (element 101) is the first actinide element found to give a divalent ion stable in solution. Reduction from the 3+ oxidation state was accomplished with Zn dust, Zn-Hg amalgam, Cr2+, Eu2+, and V2+; additionally, measurements of the equilibrium with V2+ provided an estimate of +0.2 volt for the couple, Md2+ = Md3+ + e-. The chemical behavior of Md3+ is similar to that of the other trivalent actinides and lanthanides. Oxidation from the trivalent to higher valence states with sodium bismuthate was not detected.
