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

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

Match the following

(a)   states that we can know the position or the momentum of an electron in an atom, but not both. The more you know of one characteristic, the less you know of the other.

• Heisenberg Uncertainty Principle
• Aufbau Principle
• Hund's Rule
