Electron shell
From Wikimedia Commons, the free media repository
The chemical elements represented by their electron shell diagrams, which are sorted by atomic number. Note: these images are extremly 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.
