The '''Pauli Exclusion Principle''' states that no two [[electron]]s in the same [[atom]] can have the same set of quantum numbers. This set is made up of

* [[Principle quantum number]] ''n'': this is the shell around the atom where the electron exists. The shells are represented by whole numbers. n can be 1,2,3....

* [[Principal quantum number]] ''n'': this is the shell around the atom where the electron exists. The shells are represented by whole numbers. n can be 1,2,3....

* [[Orbital quantum number]] ''l'' is the number of subshells within a shell. l can be 0,1... to (n-1)

* Orbital quantum number ''l'' is the number of subshells within a shell. l can be 0,1... to (n-1)

* [[Magnetic quantum number]] ''m_l'' is the number of orbitals within the subshell. m_l can be 0,1...all the way to ⁺/_- l

* Magnetic quantum number ''m_l'' is the number of orbitals within the subshell. m_l can be 0,1...all the way to ⁺/_- l

* [[Spin quantum number]] ''m_s'' is the spin of the electron. there are two spins per subshell. they are represented by a +1/2 or -1/2

* Spin quantum number ''m_s'' is the spin of the electron. there are two spins per subshell. they are represented by a +1/2 or -1/2

The Pauli exclusion principle follows from the requirement that fermions must have antisymmetric wavefunctions.
