### Understanding Electron Configuration Through Pauli's Principle**According to Pauli's principle,** - _"no two electrons have the same four quantum numbers."_**This means that each atomic orbital can hold at most** - _"two electrons."_**Since each molecular orbital can hold** - _"two electrons"_ **number of electrons, Pauli's principle** - _"does"_ **apply to molecular orbitals.** ### Cheat Sheet:1. **Pauli's Exclusion Principle:** - No two electrons in an atom can have identical quantum numbers; thus, a maximum of two electrons can occupy a single atomic orbital, and they must have opposite spins.2. **Electron Filling Order:** - Electrons fill lower-energy orbitals before filling higher-energy ones.3. **Hund's Rule:** - Electrons will occupy degenerate orbitals singly before pairing up, to minimize electron-electron repulsions.By understanding these fundamental rules, students can predict the electron configuration of atoms and molecules, which is crucial in understanding chemical bonding and reactions.
