The correct Answer is:
To determine which set of quantum numbers is inconsistent with the theory, we will analyze each option based on the rules of quantum mechanics. ### Step-by-step Solution: 1. **Understand Quantum Numbers**: - The principal quantum number (n) can take positive integer values (1, 2, 3, ...). - The azimuthal quantum number (l) can take values from 0 to (n-1). - The magnetic quantum number (m_l) can take values from -l to +l. - The spin quantum number (s) can be either +1/2 or -1/2. 2. **Evaluate Option 1**: - Given: n = 3, l = 2, m_l = -3, s = +1/2. - For n = 3, l can be 0, 1, or 2 (valid). - For l = 2, m_l can be -2, -1, 0, +1, or +2 (invalid since m_l = -3 is not allowed). - **Conclusion**: This option is inconsistent. 3. **Evaluate Option 2**: - Given: n = 4, l = 3, m_l = 3, s = +1/2. - For n = 4, l can be 0, 1, 2, or 3 (valid). - For l = 3, m_l can be -3, -2, -1, 0, +1, +2, or +3 (valid). - **Conclusion**: This option is consistent. 4. **Evaluate Option 3**: - Given: n = 2, l = 1, m_l = 0, s = -1/2. - For n = 2, l can be 0 or 1 (valid). - For l = 1, m_l can be -1, 0, or +1 (valid). - **Conclusion**: This option is consistent. 5. **Evaluate Option 4**: - Given: n = 4, l = 3, m_l = 2, s = unspecified. - For n = 4, l can be 0, 1, 2, or 3 (valid). - For l = 3, m_l can be -3, -2, -1, 0, +1, +2, or +3 (valid). - **Conclusion**: This option is consistent. ### Final Conclusion: The only inconsistent set of quantum numbers is from **Option 1** (n = 3, l = 2, m_l = -3, s = +1/2). ---
