Read each question carefully and provide the best answer. Show your work for any orbital diagrams.
1. Which principle states that electrons will occupy the lowest energy orbitals available first?
Pauli Exclusion Principle
Hund's Rule
Aufbau Principle
Heisenberg Uncertainty Principle
2. How many electrons can a single atomic orbital hold?
1
2
6
8
3. According to Hund's Rule, electrons will occupy degenerate orbitals singly before pairing up, and all of these single electrons will have the same .
4. The Pauli Exclusion Principle states that no two electrons in the same atom can have the same set of four numbers.
5. Draw the orbital diagram for an atom of Oxygen (O).
6. Write the electron configuration for an atom of Nitrogen (N).
7. The 3p orbital can hold a maximum of 6 electrons.
True
False
8. The 's' sublevel always contains three orbitals.
True
False
