Recent chemical investigations of the heaviest elements in aqueous-phases at JAEA are reviewed. Typically interesting results are that fluoride complex formation of element 104, Rf, is significantly different from that of the homologues, and that anionic fluoride complexation of element 105, Db, is considerably different from that of the group-5 homologue Ta while the behavior of Db is similar to that of the lighter homologue Nb. Oxidation of element 102, No, has also been successfully conducted based on an atom-at-a-time scale. Prospects for the future studies on redox properties of the heaviest elements will be briefly considered.
