Nuclear energy

 Binding energy:

1. Atomic mass unit - u          Einstein mass energy formula             eV - unit             u*c^2 - value

2. Mass defect and binding energy/ energy  of formation          Total ionization energy        Binding energy per nucleon    

3. Conditions for energy released in fusion or  fission

   • More mass before or

   • More binding energy/mass defect  after, Energy released is the change of the total binding energy

4. **Some binding energy models

   •  Liquid drop model

   • Fermi gas model  and potential well   Ground state    Fermi energy    Energy for excitation

   • Shell model  and harmonic oscillator
