TechnoratiElement 112 (ununbium)
Darmstadt, June 10, 2009
The new element 112 discovered by GSI has been officially recognized and will be named by the Darmstadt group in due course. Their suggestion should be made public over this summer.
The element 112, discovered at the GSI Helmholtzzentrum für Schwerionenforschung (Centre for Heavy Ion Research) 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.
Re: new element officially
Re: new element officially recognized:
Mendeleev has been credited as the creator of the periodic table, but shouldn't 19th century chemist Newlands as in "Newlands' Law of Octaves"
be credited as a co-discoverer? I seem to recall that he used
his law to predict new elements--which he called "Eka-Aluminum",
etc. Try googling Newlands Octaves for more info.
Your memory is faulty;
Your memory is faulty; Newland's casual observation about repeated octaves breaks down very quickly and has none of the predictive power of Mendeleev's law, nor were Newland's observations of repeated patterns substantially correlated with any other property unlike Mendeleev's periodic similarities in chemical properties, especially the empirical formulae of the oxides, which he correlated with atomic weight (actually as we now know it is Z the proton number of the nucleus). It was also Mendeleev who had the audacity to question the accuracy of some of the published atomic weights that were not in conformity with his law (and in most cases he was right) and to predict eka-aluminum (element 31), eka-silicon (element 32), eka-boron (element 21) which were soon discovered as well as eka-manganese (element 43) and dvi-manganese (element 75) which were not discovered until the twentieth century. There is no comparison between their work.
