Gesellschaft fur Schwerionenforschung (GSI) in Darmstadt, Germany is the hot bed for discovering and confirming new elements. On November 9th, 1994 the first atom with atomic number 110 was discovered...later confirmed and named in 2003 as Darmstatdium; on December 8th, 1994 the first atom with atomic number 111 was discovered...later confirmed and named in 2003 as Roentgenium. And now, number 112 has been confirmed. No name has been designated at this time.
The element 112, discovered at the Centre for Heavy Ion Research (GSI Helmholtzzentrum für Schwerionenforschung) in Darmstadt, has been officially recognized as a new element by the International Union of Pure and Applied Chemistry (IUPAC). IUPAC confirmed the recognition of element 112 in an official letter to the head of the discovering team, Professor Sigurd Hofmann. The letter furthermore asks the discoverers to propose a name for the new element. Their suggestion will be submitted within the next weeks. In about 6 months, after the proposed name has been thoroughly assessed by IUPAC, the element will receive its official name. The new element is approximately 277 times heavier than hydrogen, making it the heaviest element in the periodic table.
"We are delighted that now the sixth element -and thus all of the elements discovered at GSI during the past 30 years- has been officially recognized. During the next few weeks, the scientists of the discovering team will deliberate on a name for the new element", says Sigurd Hofmann. 21 scientists from Germany, Finland, Russia and Slovakia were involved in the experiments around the discovery of the new element 112.
Already in 1996, Professor Sigurd Hofmann's international team created the first atom of element 112 with the accelerator at GSI. In 2002, they were able to produce another atom. Subsequent accelerator experiments at the Japanese RIKEN Discovery Research Institute produced more atoms of element 112, unequivocally confirming GSI's discovery.
To produce element 112 atoms, scientists accelerate charged zinc atoms -zinc ions for short- with the help of the 120 m long particle accelerator at GSI and "fire" them onto a lead target. The zinc and lead nuclei merge in a nuclear fusion to form the nucleus of the new element. Its so-called atomic number 112, hence the provisional name "element 112", is the sum of the atomic numbers of the two initial elements: zinc has the atomic number 30 and lead the atomic number 82. An element's atomic number indicates the number of protons in its nucleus. The neutrons that are also located in the nucleus have no effect on the classification of the element. It is the 112 electrons, which orbit the nucleus, that determine the new element's chemical properties.
Since 1981, GSI accelerator experiments have yielded the discovery of six chemical elements, which carry the atomic numbers 107 to 112. GSI has already named their officially recognized elements 107 to 111: element 107 is called Bohrium, element 108 Hassium, element 109 Meitnerium, element 110 Darmstadtium, and element 111 is named Roentgenium.
