Read each question carefully and provide concise, accurate answers.
1. Which of the following describes the energy of an electron in an atom?
Continuously variable
Quantized
Always zero
Dependent on the electron's speed only
2. What is the maximum number of electrons that can occupy the third principal energy level (n=3)?
2
8
18
32
3. The rule states that electrons will occupy orbitals of equal energy singly before pairing up.
4. The principal quantum number (n) describes the electron's main and its relative distance from the nucleus.
5. Explain what is meant by the term 'ground state' for an electron.
6. How does an electron transition from a lower energy level to a higher energy level?
7. Refer to the diagram below showing electron shells. Answer the following questions:
a) Which shell is represented by 'n=1'?
b) How many electrons can the 'n=2' shell hold?
8. Electrons can exist in between energy levels.
True
False
9. The Aufbau principle states that electrons fill orbitals starting with the lowest available energy states before filling higher states.
True
False
10. Describe the significance of quantum numbers in determining the properties of electrons in an atom. Include an explanation of the principal, azimuthal, magnetic, and spin quantum numbers.
