Title: Critical evaluation of the chemical properties of the
transactinide elements
Task Group Chairman: J.V.
Kratz
Completion Date: 2002
Objective:
Critical evaluation of the chemical properties of elements 104, 105,
and 106
Description:
The chemical properties of the transactinide elements rutherfordium,
Rf (element 104), dubnium, Db (element 105), and seaborgium, Sg (element
106) are critically reviewed. The experimental methods to perform rapid
chemical separations on the time scale of seconds are reviewed and comments
are given on the special situation with the transactinides where chemistry
has to be studied with single atoms. It follows a systematic description
of theoretical predictions and experimental results on the chemistry
of Rf, Db, and Sg, their mutual comparison and evaluation. The literature
cited has the cutoff date of March 1999. The more recent chemical identification
of bohrium, Bh (element 107), and of hassium, Hs (element 108), should
be evaluated in a future Part II of this report.
Progress:
Project completed - IUPAC Technical Report published in Pure
Appl. Chem. 75(1),
