 Discovery Information |
| Who: Soviet scientists at the Joint Institute for Nuclear Research |
| When: 1976 |
| Where: Dubna, USSR |
|
| Name Origin |
| Named in honor of the Danish physicist Niels Bohr |
|
| Sources |
| Synthetically by bombarding Bi204 with heavy nuclei of Cr54. |
|
| Uses |
| None. |
|
| 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 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. |
| Bohrium is a synthetic element that is not occur naturally anywhere. |
| The German discoverers at GSI proposed the name Nielsbohrium (symbol Ns) after Niels Bohr. IUPAC are happy to name an element after Bohr but suggest bohrium (Bh) on the grounds that the first name of a person does not appear in the names of any other element named after a person. This seems to have been accepted by all concerned. |
| Element 107 was previously known as Unnilseptium; from the latin from "one zero seven". |
