2. Artificial Transmutation
Why should we even care to learn about artificial transmutation?

3. Involves splitting heavy nucleus into 2 lighter nuclei
Fission Reaction
(fission = division)
Involves splitting heavy nucleus into 2 lighter nuclei
235U + 1n  91Kr + 142Ba + 31n + energy 92 36 56

4. Fission Chain Reaction

5. Fission Chain Reaction
Controlled
– nuclear
power plant
Uncontrolled
– bomb

6. Fusion nuclei unite – must be small like H or He
2H + 3H  4He + 1n + energy 1 2 1
Source of sun’s energy
