Early transuranium elements. After the discovery of the neutron by Chadwick in 1932, the group led by Fermi in Rome. began bombarding different elements with neutrons to study the radioactivity induced through. (n,() reactions. The decay characteristics of the radioactivity in neutron-irradiated uranium was. interpreted to indicate that some of the products were probably transuranium elements. Similar. conclusions were reached by other research groups; for example in 1937 Meitner, Hahn and.
Back in 2010, a group of American and Russian scientists first discovered element 117 in a joint collaboration. Temporarily known as ununseptium, the super heavy element is created by bombarding Berkelium (atomic number 97) with Calcium ions at high speed, according to Forbes.cientists even discovered the element through its decay. However, through their discovery scientists also found that two isotopes produced during decay are isotopes of elements 103 and 105, which are among the most stable super heavy isotopes.
