Talk:Ununseptium

In April of 2010, a team of Physicists from the Joint Institute for Nuclear Research in Dubna, Russia reported finding evidence of element number 117. They used a target of 22 milligrams of berkelium-249, element 97, obtained from Oakridge National Laboratory and used a beam of Calcium ions to bombard it.

They produced evidence for two different isotopes of element 117, one with atomic weight of 293 (117 protons and 176 neutrons) which had a half-life of 14 milliseconds and the other with weight of 294, with half-life of 78 milliseconds.

The element is not yet officially named.
