The Aufbau principle can be applied, in a modified form, to the protons and neutrons in the atomic nucleus, as in the shell model of nuclear physics and nuclear chemistry.

The relativistic stabilization of the 7s orbital is the explanation to the predicted electron configuration of darmstadtium, which, unusually for this group, conforms to that predicted by the Aufbau principle.
13.
The outer electron configuration of darmstadtium is calculated to be 6d 8 7s 2, which obeys the Aufbau principle and does not follow platinum's outer electron configuration of 5d 9 6s 1.

Can someone please give me a step-by-step method of how to write the electron configuration of any atom; one way according that doesn't follow the Aufbau principle and another that does.
15.
This is due to the relativistic stabilization of the 7s 2 electron pair over the whole seventh period, so that none of the elements from 104 to 112 are expected to have electron configurations violating the Aufbau principle.

The following is the order for filling the " subshell " orbitals, according to the Aufbau principle, which also gives the linear order of the " blocks " ( as atomic number increases ) in the periodic table:
17.
A simple extrapolation from the Aufbau principle would predict the eighth row to fill orbitals in the order 8s, 5g, 6f, 7d, 8p; but after element 120, the proximity of the electron shells makes placement in a simple table problematic.
18.
The fact that the Aufbau principle is based on an approximation can be seen from the fact that there is an almost-fixed filling order at all, that, within a given shell, the s-orbital is always filled before the p-orbitals.
19.
Although this is the general order of orbital filling according to the Madelung rule, there are exceptions, and the actual electronic energies of each element are also dependent upon additional details of the atoms ( see Electron configuration # Atoms : Aufbau principle and Madelung rule ).

The first excited state ( Aufbau principle, ibid . ) is 2s and the second excited state is 2p . ( Unless there's a strong magnetic field which would induce the Zeeman effect . ) By reference to the Lyman series, we may estimate the change in potential energy of the electron in the potential of a single proton ( a . k . a.
