Borhium

• Atomic Number: 107

  Atomic Symbol: Bh

  Atomic Weight: (262)

History:

• In 1976 Soviet scientists at Dubna announced they had synthesized Borhium by bombarding 204Bi with heavy nuclei of 54Cr. It is reported that earlier experiments in 1975 had allowed scientists "to glimpse" the new element for 2/1000 s. A rapidly rotating cylinder, coated with a thin layer of bismuth metal, was used as a target. This was bombarded by a stream of 54Cr ions fired tangentially. The existence of Borhium was confirmed by a team of West German physicists at the Heavy Ion Research Laboratory at Darmstadt, who created and identified six nuclei of Borhium.
