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
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]] <i>n</i>: 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]] <i>l</i> is the number of subshells within a shell. l can be 0,1... to (n-1)
* [[Magnetic quantum number]] <i>m<sub>l</sub></i> is the number of orbitals within the subshell. m<sub>l</sub> can be 0,1...all the way to <sup>+</sup>/<sub>-</sub> l
* [[Spin quantum number]] m<sub>s</sub> is the spin of the electron. there are two spins per subshell. they are represented by a +1/2 or -1/2
