For the third shell, $n=3$, so the allowed values of $\ell$ are: $\ell=0$, which is the $s$ subshell, $\ell=1$, which is the $p$ subshell, and $\ell=2$, which is the $d$ subshell. This is demonstrated in Figure 2. The orbital energy levels are always in the following order: -1s 2s = 2p 3s = 3p = 3d 4s = 4p = 4d= 4f A degenerate orbital is one that has the same energy as another orbital. The Pauli Exclusion Principle states that no two electrons in the same atom can have the exact same set of quantum numbers. An example is the 2p orbital: 2px has the same energy level as 2py. So, the next three electrons will enter the 4p orbital in the clockwise direction and the remaining one electron will enter the 4p orbital in the anti-clockwise direction. This means that for a d subshell , the magnetic quantum number can take 5 possible values. For example the s subshell can hold a total of 2 electrons.
