Aufbau Principle
Orbitals are filled with electrons in increasing energy.
Madelung's Rule
Orbitals with lower n + l values are filled first.
Hund's Rule
The most stable arrangement of electrons in subshells is the one with the greatest number of parallel spins.
Pauli's Exclusion Principle
An orbital must contain a maximum of two electrons with opposite spins; hence, no two electrons can have the same set of quantum numbers.
Ground State Electron Configuration
Electron configurations follow specific principles
