Electron shell
.svg)
The chemical elements represented by their electron shell diagrams, which are sorted by atomic number. Note: these images are extremely simplified from reality and should only be used to illustrate the number of electrons in their shells.
There is an alternative sorting of the elements at Periodic table samples.
As of October 2012, the kernel colors represent a subcategory in the range metal–metalloid–nonmetal, as used in the legend in the English Wikipedia [1].
