The correct Answer is:
To solve the question of selecting the correct set(s) of quantum numbers, we will follow a systematic approach based on the rules governing quantum numbers. ### Step-by-Step Solution: 1. **Understand the Quantum Numbers**: - There are four types of quantum numbers: - **Principal Quantum Number (n)**: Indicates the shell and size of the orbital. It can take positive integer values (1, 2, 3,...). - **Azimuthal Quantum Number (l)**: Indicates the shape of the orbital. It can take values from 0 to n-1. - **Magnetic Quantum Number (ml)**: Indicates the orientation of the orbital. It can take values from -l to +l. - **Spin Quantum Number (s)**: Indicates the spin of the electron, which can be +1/2 or -1/2. 2. **Evaluate Each Option**: - **Option A**: n = 3, l = 0, ml = -1 - Here, l = 0 corresponds to an s orbital (3s). - The value of ml for l = 0 can only be 0. Therefore, ml = -1 is incorrect. - **Option B**: n = 3, l = 3 - The maximum value of l can be n-1. For n = 3, l can only be 0, 1, or 2. Hence, l = 3 is incorrect. - **Option C**: n = 3, l = 2, ml = -2 - Here, l = 2 corresponds to a d orbital. - The values of ml can range from -2 to +2 (i.e., -2, -1, 0, +1, +2). Therefore, ml = -2 is correct. - **Option D**: n = 3, l = 1, ml = 0 - Here, l = 1 corresponds to a p orbital. - The values of ml can range from -1 to +1 (i.e., -1, 0, +1). Therefore, ml = 0 is correct. 3. **Conclusion**: - The correct sets of quantum numbers are found in options C and D. ### Final Answer: The correct sets of quantum numbers are **Option C** (n = 3, l = 2, ml = -2) and **Option D** (n = 3, l = 1, ml = 0). ---
