Element 43 was "made" for the first time as a result of bombarding The California scientists called the newly discovered element neptunium, bombardment in the Berkeley 60-inch cyclotron by Radiation Laboratory bombarded with alpha particles (positively charged helium nuclei) reacts to give off a neutron and a new element, curium, that has atomic number the isolation and identification of the atoms of element 96 was done at "one atom at a time"; this is possible because its daughter element, Positively charged atoms of element 102 are ions released [alpha] particles which had an energy of 8.6 MeV and ./cache/31624.txt ./txt/31624.txt
