The helium atom contains two protons and two electrons. The first electron has the same four quantum numbers as the hydrogen atom electron ( n = 1, l = 0, ml = 0, ms = +1 2 m s = + 1 2 ).The reason we see these Aufbau's principle exceptions in transition metals is because the $4s$ and $3d$ orbitals are very similar in energy.. In chromium, having a $4s^2$ $3d^4$ configuration results in electron-electron repulsion due to the two electrons in the $4s$ orbital. For this reason, chromium adopts a $4s^1$ $3d^5$ configuration, in which each electron occupies its own orbital.With two important exceptions, the 3d subshell is filled as expected based on the aufbau principle and Hund's rule. Unexpectedly, however, chromium has a 4s 1 3d 5 electron configuration rather than the 4s 2 3d 4 configuration predicted by the aufbau principle, and copper is 4s 1 3d 10 rather than 4s 2 3d 9.
