The Pauli Exclusion Principle states that no two electrons in the same atom can have the same set of quantum numbers. This set is made up of
- 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....
- l: this is the number of subshells within a shell. l can be 0,1...all the way to (n-1)
- ml: this is the number of orbitals within the subshell. ml can be 0,1...all the way to +/- l
- ms is the spin of the electron. there are two spins per subshell. they are represented by a +1/2 or -1/2
