  • Nuclear fission/ fussion
    • Fission
      • There are two fissionable substances in common use in the nuclear reactors: uranium and plutonium.
        • The majority of nuclear reactors use uranium.
      • Nuclear fission is the splitting of an atomic nucleus
      • For fission to occur the uranium or pltioium nucleus must first absorb a neutron
      • The nucleus undergoing fission spilts into two smaller nuclei and two or three neutrons and energy is realesed.
      • The neutrons may go on to start a chain reaction
        • We must be able to draw a chain reactor.
    • Fusion
      • Nuclear fusion is the joining of two atomic nuclei to form a larger one.
      • Nuclear fusion is the process by which energy is released in stars.
      • Stars form when enough dust and gas from space is pulled together by gravitational attraction.
        • Smaller also  masses may form and be attracted by a larger mass to become plantets
      • Durin period of its life cycle. This life cycle is determined  by the size of the star.
      • Fusion processes in stars produce all of the naturally ocurring elements.
