Term 2 Week 6 2017

Homework
  • Ex 5A, p. 151-155, Models of the Atom
  • Ex 5B, p. 160-171, Radioactivity
  • Ex 5C, p. 175-182, Nuclear Reactions
Chem/Phy Canterbury Field Trip this Thursday-Friday

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


Mass Energy Equivalence
