However there are numerous exceptions; for example the lightest exception is chromium, which would be predicted to have the configuration 1s 2 2s 2 2p 6 3s 2 3p 6 3d 4 4s 2, written as [Ar] 3d 4 4s 2, but whose actual configuration given in the table below is [Ar] 3d 5 4s 1.

In hydrogen, the electron will have the same energy in either the 2s or the 2p orbital (but see NOTE below). However, hydrogen (and ions with just one electron) is the exception. When an atom has more than one electron, the 2s orbital is a bit lower in energy than the 2p orbital. My chemistry book explains that even though electrons in the 2 p orbital are closer to the nucleus on average, electrons from the 2 s orbital spend a very short time very close to the nucleus (penetration), so it has a lower energy. Why does this tiny amount of time spent close to the nucleus make such a big difference? The arrow goes through 1s first, then 2s, then 2p & 3s, then 3p & 4s, then 3d, 4p, & 5s, and so on.

Det nästa skalet är L-skalet. I atomer finns det stora skillnader in bindningsenergi mellan 2s- och 2p-orbitaler. Eftersom s-orbitaler har högre sannolikhetstäthet på

Instead of relying on memorization, you can use the memory aid shown below to remind you of the correct order of filling of the sublevels. The following steps explain how to write it and use it yourself.
