Describes how electrons are distributed in atomic orbitals.

• Electron Configurations

• Molecular Mass

It states that within a subshell, electrons will first fill each orbital with one spin before pairing with spin down.

• Pauli Exclusion Principle

• Hund's Rule

It states that an orbital can contain a maximum of only two electrons, and these two electrons must have opposing spins.
