The correct Answer is:
To determine the shell occupied by an electron given its quantum numbers, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Principal Quantum Number (n)**: - The principal quantum number \( n \) indicates the shell in which the electron is located. In this case, \( n = 3 \). 2. **Relate the Principal Quantum Number to Shells**: - The shells are designated as follows: - \( n = 1 \) corresponds to the K shell - \( n = 2 \) corresponds to the L shell - \( n = 3 \) corresponds to the M shell - \( n = 4 \) corresponds to the N shell - Since \( n = 3 \), the electron is in the M shell. 3. **Conclusion**: - Therefore, the electron with the given quantum numbers is occupying the M shell. ### Final Answer: The electron is occupying the M shell. ---
