TRANSCRIPT

- Slide 1
- Nuclear Fission and Fusion
- Slide 2
- Nuclear Fission Nuclear Fission: The splitting of a massive nucleus into two smaller nuclei
- Slide 3
- Nuclear Fission Nuclear Fission: The splitting of a massive nucleus into two smaller nuclei Nuclear Fission and Energy: The splitting of atoms produces a large amount of energy. This energy is produced in nuclear power plants
- Slide 4
- Nuclear Fission Nuclear Fission: The splitting of a massive nucleus into two smaller nuclei Nuclear Fission and Energy: The splitting of atoms produces a large amount of energy. This energy is produced in nuclear power plants Problems with nuclear power: The waste produced has to be safely stored for thousands of years.
- Slide 5
- Nuclear Reactions Nuclear Reactions: When an atoms nucleus changes by gaining or releasing particles or energy. Particles released: Protons, neutrons and or electrons
- Slide 6
- Particles released in nuclear reactions
- Slide 7
- Rules for writing nuclear equations The sum of the mass numbers must be the same on both sides The sum of the charges (atomic number) must be the same.
- Slide 8
- Fission reaction
- Slide 9
- Chain reactions and weapons Chain reaction: when one fission reaction stimulates the next reaction (eg a neutron from one will join to another nuclei causing it to split)
- Slide 10
- Chain Reaction h
- Slide 11
- Nuclear Fusion Nuclear Fusion: The opposite of nuclear fission - When two smaller nuclei fuse to form one larger one
