How Electrons Fill the Orbitals – the rules
The orbitals are present on every atom, but only some have electrons located in them depending on how many electrons the atom has. Three guiding principles to use: 1) Aufbau Principle: Electrons live in the lowest energy orbitals possible. (Higher energy orbitals remain empty.) “Aufbau” is German for construction. 2) Pauli Exclusion principle: No two electrons can have the same 4 quantum numbers. Orbitals can hold up to 2 electrons. 3) Hund’s Rule: (Seats on a Bus rule) Electrons will fill orbitals of a subshell singly before pairing up. If paired, they have opposite spins.
