Question
When writing the ground-state electron configuration of a many-electron atom, three main rules must be followed:
. The aufbau principle: Electrons are added to the lowest energy orbitals available.
. The Pauli exclusion principle: No two electrons in an atom can have the same set of four quantum numbers (n. l. me, and m₂).
• Hund's rule: For degenerate orbitals, the lowest energy state is attained when the number of electrons with the same spin is maximized. So for a degenerate set of orbitals, one electron goes into each orbital until all the orbitals
of the subshell are half-filled. Once all the orbitals of the subshell are half-filled the pairing of electrons can take place.
Note that aufbau is the German word for "building up."
