Periodic table (electron configurations)
- Grayed out electron numbers indicate subshells that are filled to their maximum.
- Configurations of elements with light gray background are uncertain or not available.
Additional recommended knowledge
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
- Note the non-linear shell ordering, which comes about is due to the different energies of smaller and larger shells.
