Three New Elements Added To Periodic Table
2011-11-06 05:55:17

The Periodic Table has gotten a little bit bigger, as the General Assembly of the International Union of Pure and Applied Physics (IUPAP) voted to approve three new elements on Friday. Those elements, according to Dennis Overbye of the New York Times, are darmstadtium (Ds), roentgenium (Rg), and copernicium (Cn), which have 110, 111, and 112 protons, respectively. None of the elements occur in nature. Rather, they were created at the GSI Society for Heavy Ion Research Laboratory in...

Scientists from the scientific governing committees of physics and chemistry have added two new elements -- yet to be named -- to the periodic table, reports The Associated Press (AP). The elements, currently known only as 114 and 116, are both highly radioactive and, with respective atomic weights of 289 and 292, are now the heaviest elements on the periodic table of elements, bumping copernicium and roentgenium down the list of heavyweights. The two radioactive elements exist only for a...

Moving Closer to Understanding the Island of Stability A team of scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory has detected six isotopes, never seen before, of the superheavy elements 104 through 114. Starting with the creation of a new isotope of the yet-to-be-named element 114, the researchers observed successive emissions of alpha particles that yielded new isotopes of copernicium (element 112), darmstadtium (element 110), hassium (element 108),...

One of the heaviest elements At GSI Helmholtzzentrum fr Schwerionenforschung, an international team of scientists succeeded in the observation of the chemical element 114, one of the heaviest elements created until now. The production of element 114 is very difficult and requires dedicated particle accelerators. So far, this feat was achieved at only two other research centers, in the USA and Russia. In the experiment at GSI, scientists employed the innovative new setup TASCA (TransActinide...

Element 117 fills in the final gap in the list of observed elements up to element 118 A collaboration of Russian and US physicists has finally created element 117 - a superheavy element made of atoms containing 117 protons that is roughly 40% heavier than lead. The achievement fills in the final gap on the list of observed elements up to element 118. The team produced the elusive element 117 by fusing together atoms of calcium and another rare, heavy element known as berkelium. The research...

The name proposed by GSI for the heaviest chemical element has been officially endorsed The heaviest recognized chemical element with the atomic number 112 was discovered at the GSI Helmholtzzentrum fr Schwerionenforschung and "“ since February 19, 2010 "“ officially carries the name copernicium and the chemical symbol "Cn". The name was approved and officially announced today by the international union for chemistry IUPAC*. The name "Copernicium" honors scientist and astronomer...

U.S. scientists say they have confirmed the production of the superheavy element 114, 10 years after a Russian group first claimed to have made it. The researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, led by University of California-Berkeley Professor Heino Nitsche and and Berekely Lab senior staff scientist Ken Gregorich, independently confirmed the production of the new element, which was first published by the Dubna Gas Filled Recoil Separator group....

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have been able to confirm the production of the superheavy element 114, ten years after a group in Russia, at the Joint Institute for Nuclear Research in Dubna, first claimed to have made it. The search for 114 has long been a key part of the quest for nuclear science's hoped-for Island of Stability. Heino Nitsche, head of the Heavy Element Nuclear and Radiochemistry Group in Berkeley Lab's Nuclear Science...

In honor of scientist and astronomer Nicolaus Copernicus (1473-1543), the discovering team around Professor Sigurd Hofmann suggested the name "žcopernicium" with the element symbol "Cp" for the new element 112, discovered at the GSI Helmholtzzentrum fr Schwerionenforschung (Center for Heavy Ion Research) in Darmstadt. It was Copernicus who discovered that the Earth orbits the Sun, thus paving the way for our modern view of the world. Thirteen years ago, element 112 was...

A team of German scientists has been credited with the discovery of the new "super-heavy" element 112 more than ten years after intensive laboratory work first yielded a single atom of the novel form of matter. But before the element can be officially added to the periodic table, Sigurd Hofmann and his team of researchers at the Center for Heavy Ion Research in Darmstadt, Germany have to think of a name for their discovery. Professor Hofmann's pursuit to expand the periodic table first...
