Alphabetical Electron Configuration List of all Elements

Alphabetical Electron Configuration List of all Elements This is an alphabetical electron configuration list of all the elements of the periodic table. While the electronic structure of the lighter elements is well-studied, once you get to the heavier man-made elements, these configurations are predicted or calculated based on periodic table trends. Configurations are estimated from dubnium (element 105) up to ununoctium (element 118). Note the configurations are listed using the noble gas core notation. So, for example, neon is written using this shorthand as [He]2s22p6 rather than 1s22s22p6. The electron configurations of the newly discovered super-heavy elements are predicted. Electrons travel at relativistic speeds in these atoms, so unusual behavior might occur. You may also view the electron configurations of the first 104 elements in order of atomic number.
