Element 112In 1996, only a little more than a year after they created element 111, a team of German scientists led by Peter Armbruster at the Gesellschaft für schwerionenforschung (GSI) facility at Darmstadt, Germany, claimed to have created an atom of the element 112. Its nucleus has 112 protons and 166 neutrons, giving it a mass number of 277. As a new element it was named ununbium, symbol Uub, according to an internationally adopted system for naming new elements. This was based on the presence of one atom of the element made by accelerating zinc atoms to high speed and bombarding them into lead. When an atom of each fused to make the new nucleus, it lasted a fraction of a thousandth of a second before decaying, emitting an alpha particle to become a nucleus of element 110. |
