 2 ) in aqueous solution, analogous to plumbite. Flerovium (II) sulfate (FlSO4) and sulfide (FlS) should be very insoluble in water, and flerovium (II) acetate (FlC2H3O2) and nitrate (Fl ( NO3) 2 ) should be quite water-soluble. The standard electrode potential for the reduction of Fl2 + ions to metallic flerovium is estimated to be around + 0.9 V, confirming the increased stability of flerovium in the neutral state. In general, due to the relativistic stabilization of the 7p1 / 2 spinor, Fl2 + is expected to have properties intermediate between those of Hg2 + or Cd2 + and its lighter congener Pb2 +.
