pauli exclusion principle

pauli exclusion principle

1. say that two atoms can not have the same four electronic quantum numbers

2. and if they are in the last orbit they need to have opposing spins

3. all this happens in an atom

4. there are two classes of subatomic particles

   • fermions
     • include all quarks and leptons as well as a composite particle made of an odd number
   • bosons
     • include fundamental particles as photons ,gluons andw and z bosons
