Electrons in Atoms

An electron occupies the lowest energy orbital that can receive it.

• Hund’s rule
• Pauli exclusion principle
• Bohr model of the atom
• Aufbau principle

All orbitals of equal energy are occupied by one electron before any single orbital is occupied by a second electron.

• Aufbau principle
• Pauli exclusion principle
• Hund’s rule
• Core Notation

An orbital can hold at most 2 electrons, and when paired in the same orbital electrons spin in opposite directions.
