Answer Key for Incorrect Questions
Q3. Neon electron configuration?
Correct Answer: 1s² 2s² 2p⁶
Teacher's Note: Remember that noble gases have completely filled orbitals. Neon has 10 electrons total.
Q4. Orbitals in p sublevel?
Correct Answer: 3 orbitals (px, py, pz)
Teacher's Note: Each sublevel has a specific number of orbitals: s=1, p=3, d=5, f=7.
Q5. Explain Aufbau principle
Correct Answer: Electrons occupy orbitals of lowest energy first
Teacher's Note: This principle explains the order in which electrons fill atomic orbitals. Practice drawing the orbital filling diagram.
