This method usually involves isotopes of uranium (uranium-235, uranium-233) or plutonium (plutonium-239). Uranium-235 exists in only 0.7 percent of natural uranium ore; the other 99.3 percent is uranium-238, a more stable isotope that tends to absorb neutrons rather than split and that can keep chain reactions from even reaching the critical stage. In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy. When an atom splits into two parts, either through natural decay or when instigated within a lab, it releases energy. When a uranium atom splits it gives off more neutrons, which can then split more atoms, and so the energy level rapidly multiplies. 1939: Austrian-born physicist Lise Meitner publishes her discovery that atomic nuclei split during some uranium reactions.
