Madelung's Rule

Orbitals with lower n + l values are filled first.

3
New cards

Hund's Rule

The most stable arrangement of electrons in subshells is the one with the greatest number of parallel spins.

New cards

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.
