Pauli exclusion principle

Pauli exclusion principle

1. Is the quantum mechanical principle that says that 2

   • identical fermions cant occupy the same quantum state
   • It is imposible for 2 electrons to have the same values
     • of the quantum numbers
       • Quantum numbers: n, l, ml
       • Bosons arent subject of Pauli exclusion...
         • Any # of identical bosons can occupy the same quantum state
           • Pauli...governs the behavior of all fermions*
             • Fermions: any particle.  includes elementary particles: quarks, electrons and neutrinos and some atoms   
             • Atoms can have different overall spin which determines wether they are fermions or bosons
