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.
(Latin Germania, Germany) Mendeleev predicted the existence of Germanium in 1871 as ekasilicon, and the element was discovered by Winkler in 1886. 1  argyrodite, a sulfide of germanium and silver; 2  germanite, which contains 8 percent of the element;3  zinc ores;4  coal; and.one-refining techniques have led to production of crystalline germanium for semiconductor use with an impurity of only one part in 1010.UsesWhen germanium is doped with arsenic, gallium, or other elements, it is used as a transistor element in thousands of electronic applications.
