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.
Nuclear Reactions
Nuclear Reactions: When an atom’s nucleus changes by gaining or releasing particles or energy.
Particles released: Protons, neutrons and or electrons
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.
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)
