Anionic Fluoro Complex of Element 105, Db

Anionic Fluoro Complex of Element 105, Db

We report on the characteristic anion-exchange behavior of the superheavy element dubnium (Db) with atomic number Z=105 in HF/HNO3 solution at the fluoride ion concentration [F−]=0.003 M. The result clearly demonstrates that the fluoro complex formation of Db is significantly different from that of...

Zusammenfassung:We report on the characteristic anion-exchange behavior of the superheavy element dubnium (Db) with atomic number Z=105 in HF/HNO3 solution at the fluoride ion concentration [F−]=0.003 M. The result clearly demonstrates that the fluoro complex formation of Db is significantly different from that of the group-5 homologue Ta in the 6th period of the periodic table while the behavior of Db is similar to that of the lighter homologue Nb in the 5th period.
