 Discovery Information
|
| Who: GSI |
| When: Feb 9th 1996 |
| Where: GSI, Darmstadt, Germany |
| Name Origin
|
| From the latin for "one one two". |
| Sources
|
| Element 112 was discovered on 9th February 1996 at 22:37 at the GSI in Darmstadt, Germany. |
| Uses
|
| None. |
| Notes
|
| As only a few atoms of element 112 have ever been made (through a nuclear reaction involving fusing a zinc atom with a lead atom) isolation of an observable quantity has never been achieved, and may well never be. This is because atoms of the element decompose through the emission of a-particles with a half life of only about 240 microseconds. |
