In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary ...

Not that electronic configuration is perfect either, as Scerri will tell you. Exceptions have been made for some elements in the periodic table in terms of how their orbitals are filled, like copper.

Uranium, belonging to the periodic table´s actinide elements, has long intrigued scientists due to its complex electron configurations. Its unusual and diverse bonding characteristic manifests ...
