Scientists have created six new isotopes of the superheavy elements, reaching in an unbroken chain of decays from element 114 down to rutherfordium. The discovery is a major step toward understanding ...

Carolyn Krause presents the second part of the three-part series on the Oak Ridge National Laboratory's role in the discovery of elements in the periodic table. Many of them have been synthesized ...

Researchers analyze the ratios of calcium isotopes in bones and fossils to learn more about what dinosaurs once ate. Credit: ...

Being unstable and stable is a relative innovation, and almost every element will decay, but for the stable ones, their half lives would extend to as long as million even billion years. All the four ...

Two isotopes of a new element with atomic number Z=117 were created by an international collaboration in the reaction between unique radioactive 249 Bk target material produced at ORNL through the DOE ...

Chemists searching for the island of stability now have a better map. Thanks to the discovery of six new variations of the superheavy elements on the bottom rung of the periodic table, scientists are ...

Berkeley, CA—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.

Six isotopes, never seen before, of the superheavy elements 104 through 114A have been detected by a team of scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory.
