    • Sources of Bohrium:
      Synthetically by bombarding Bi204 with heavy nuclei of CR54.
    • Uses of Bohrium:
    • Additional Notes:
      In 1975 Soviet scientists in Dubna were able to synthesize element 107 which then existed for only 2/1000's of a second. Physicists at the Heavy Ion Research Laboratory in Darmstadt West Germany confirmed this discovery in 1981 by synthesizing and identifying six nuclei of the element. In August of 1997 the International Union of Pure and Applied Chemistry announced the official naming of this element as Bohrium. Like many elements, the discovery date for this element varies from reference source to reference source. We speculate that this is caused by academic and geo-political rivalries.
