Chapter

Abstract

This chapter summarizes gas chemical studies of transactinides using two approaches, gas thermochromatography and isothermal gas chromatography. Both techniques enabled successful chemical studies of the transactinides, rutherfordium (Z = 104, Rf) , dubnium (Z = 105, Db), seaborgium (Z = 106, Sg), bohrium (Z = 107, Bh), hassium (Z = 108; Hs), copernicium (Z = 112, Cn), and the recently named flerovium (Z = 114, Fl). Typically, these chemical investigations were performed one-atom-at-a-time with a total of less than 20 atoms. For their synthesis, hot heavy-ion fusion reactions with actinide targets were used. The elements Rf through Hs show the typical behavior of d-elements, representing the expected trend within their respective group of the Periodic Table. The chemical species investigated were volatile halides, oxyhalides, oxide hydroxides, and oxides. The elements copernicium and flerovium were studied in their elemental state.
