3 Nuclear Fission and Fusion Fission: Splitting a heavy nucleus into two nuclei with smaller mass numbers.

4 Fission

5 Nuclear Fission & POWER Currently about 103 nuclear power plants in the U.S. and about 435 worldwide. 17% of the world’s energy comes from nuclear.

6 Nuclear Fission and Fusion Fusion: Combining two light nuclei to form a heavier, more stable nucleus.

7 Fusion The Sun

8 Energy and Mass Nuclear changes occur with small but measurable losses of mass. The mass is converted to energy according to Einstein’s equation: E = mc 2  m = mass  E = change in energy c = speed of light Because c 2 is so large, even small amounts of mass are converted to enormous amount of energy.

9 Lets do this!

10 A Fission Reactor

11 Fission Processes A self-sustaining fission process is called a chain reaction.
