Periodic table (electron configurations)


Periodic table (electron configurations)

* Configurations of elements with light gray background are uncertain or not available.

* Grayed out electron numbers indicate subshells that are filled to their maximum.Configurations that are unavailable are guessed to be similar to the element directly above on the Periodic Table.
* The bracketed noble gas symbols on the left represent the inner configurations that are the same in each period. Written out these are::: He, 2, helium : 1s2:: Ne, 10, neon : 1s2 2s2 2p6:: Ar, 18, argon : 1s2 2s2 2p6 3s2 3p6:: Kr, 36, krypton : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6:: Xe, 54, xenon : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6:: Rn, 86, radon : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6:: Uuo, 118, Ununoctium : 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6
* "Note the non-linear shell ordering, which comes about due to the different energies of smaller and larger shells."
