Joint Inst. Nucl. Res. (Dubna, U.S.S.R) Preprint D6–3281 (title) Experiments on chemistry of element 104—kurchatovium. 1968 New Scientist 11 Jan. 85/1 Scientist working..at Dubna..were last year awarded the Lenin Prize for their work on the synthesis of transuranium elements, in particular element 104. This latter element was named Kurchatovium by the Russians. 1970 Soviet Radiochem. XII. 536 It was confirmed..that kurchatovium forms a chloride KuCl4, with properties close to those of the chloride HfCl4, and, consequently, is an analog of hafnium and zirconium, i.e., a member of sub-group IVb. 1971 Inorg. & Nucl. Chem. Lett. VII. 1115 The present work shows once again that the doubts expressed by the Berkeley group..concerning the chemical identification of kurchatovium are completely unfounded. 1971 Inorg. & Nucl. Chem. Lett. VII. 1119 [Reply of the ‘Berkeley group’] We believe that these comments raise some valid questions as to whether or not ‘element 104 (kurchatovium—Ku) was chemically isolated and identified’.
