Week 7 Term 2 2025 Nuclear Reactions

Homework

Models of the Atom & Radioactivity

  • Act 15A, p.173-176 Models of the Atom and Radioactivity
  • Ex 5A, p. 151-155 Models of the Atom
  • Ex 5B, p.160-171 Radioactivity

Nuclaer Reactions
  • Act 16A, p. 181, Nuclear Reactions
  • Ex 5C, p.175-182 Nuclear Reactions

Nuclear Reactions:
  • Conservation of Atomic Number
  • Conservation of Nucleon Number
  • Conservation of Mass-Energy E = Δmc2

E = Δmc2




Nuclear Fusion in the Sun

Binding Energy comes from the change in mass from individual nucleons to being combined into a nucleus. This is energy lost by the nucleons joined together in a nucleus and must be returned in order to separate the nucleons
E = Δmc2

Element formation in Stars Nuclear Fusion



Binding Energy Per Nucleon

Mass Per Nucleon
