1. Transmutation Rutherford – 1919 How is this different than radioactivity? Not a natural occurrence Can be controlled – stopped or started Two reactants instead of one Uses bombardment by a lighter particle

2. Transmutation Chadwick - 1932

3. Transmutation Irene Curie and Frederick Joliot –1 st artificial radioactive isotope

4. Bombardment reactions Write an equation for the bombardment of Bismuth-209 with an alpha particle to produce Astatine- 211 (At) and several neutrons.

5. Fission Equation Write an equation for the bombarding of the Uranium-235 with a neutron to form Krypton having 57 neutrons and Barium having 84 neutrons along with some neutrons by themselves.
