Summary

A comparison of crystallographic radii of actinide ions with their stability in aqueous solutions shows that except for Ac/sup 3 +/ and Th/sup 4 +/, the simple actinide ions stable in aqueous solutions have ionic radii between 0.93 and 1.05 A. Extrapolation of crystal radii to the heavy actinides suggests that 2+ ions of Fm, Es, and possibly Cf could exist in aqueous solutions, and that 4+ ions of elements heavier than Cf would be unstable.
