Chemists Inch Closer to Stable Superheavy Atoms

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 closer to creating elements that are expected to last long enough for in-depth study. Researchers at Lawrence Berkeley National Laboratory in California saw the isotopes of rutherfordium, seaborgium, hassium, darmstadtium, and copernicium by watching the decay of the yet-to-be-named element 114, a synthetic element first produced about a decade ago. Each isotope of an element differs in the number of neutrons in its nucleus, a variable that can affect radioactivity and other properties. More>
