Title: Filling electron orbitals
Caption: The order in which electron orbitals are filled is shown using the periodic table as a guide.
Notes: When building an electronic configuration, electrons enter the lowest energetically available orbital. The relative energies of the orbitals therefore dictates the order of filling. Using the periodic table as a guide, the order in which the orbitals are filled is shown.
Keywords: orbital filling, electronic configuration, periodic table
