Success Criteria:
I can explain the process of nuclear fission and the conditions under which it occurs.
I can discuss the products of fission, including energy release, smaller nuclei, and neutrons.
I can explain the process of nuclear fusion and the conditions required for it to occur, including high temperature and pressure.
I can outline the steps involved in a fusion reaction, including the combining of light nuclei to form a heavier nucleus.
Fun Fact
The energy released from a small amount of fusion fuel is immense! Just one kilogram of hydrogen, when fused, can produce about the same amount of energy as 10,000 kilograms of fossil fuel. This incredible energy density makes fusion an attractive option for future energy needs!
Key terms
Nuclear Fusion: A nuclear reaction in which two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process, as seen in stars.
Nuclear Fission: A nuclear reaction in which a heavy nucleus splits into two or more lighter nuclei, along with the release of energy, neutrons, and gamma rays.
Mass Defect: The difference between the mass of an atomic nucleus and the sum of the masses of its individual protons and neutrons; this mass difference is converted into binding energy.
