Read each question carefully and provide the best answer. Show all your work for calculations and orbital diagrams.
1. Which principle states that no two electrons in the same atom can have the same four quantum numbers?
Hund's Rule
Aufbau Principle
Pauli Exclusion Principle
Heisenberg Uncertainty Principle
2. How many electrons can a single p orbital hold?
1
2
3
6
3. According to Hund's Rule, electrons will occupy separate orbitals within a subshell with parallel spins before pairing up. This is because electrons repel each other due to their charge.
4. The principal quantum number (n) describes the electron's energy level and its from the nucleus.
5. Write the full electron configuration for a neutral atom of Oxygen (O).
6. Draw the orbital notation for a neutral atom of Nitrogen (N).
7. The 3d subshell has a lower energy than the 4s subshell.
True
False
8. An electron with a spin quantum number (ms) of +1/2 is spinning in the opposite direction to an electron with ms = -1/2.
True
False
