Chemical Characterization of a Volatile Dubnium Compound, DbOCl(3)

The formation and the chemical characterization of single atoms of dubnium (Db, element 105), in the form of its volatile oxychloride, was investigated using the on‐line gas phase chromatography technique, in the temperature range 350–600 °C. Under the exactly same chemical conditions, comparative s...

Descripción
Sumario:The formation and the chemical characterization of single atoms of dubnium (Db, element 105), in the form of its volatile oxychloride, was investigated using the on‐line gas phase chromatography technique, in the temperature range 350–600 °C. Under the exactly same chemical conditions, comparative studies with the lighter homologues of Group 5 in the Periodic Table clearly indicate the volatility sequence being NbOCl(3) > TaOCl(3) ≥ DbOCl(3). From the obtained experimental results, thermochemical data for DbOCl(3) were derived. The present study delivers reliable experimental information for theoretical calculations on chemical properties of transactinides.
