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

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

Fission Chain Reaction

Fission Chain Reaction Controlled – nuclear power plant Uncontrolled – bomb

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