The correct Answer is:
To determine which set of quantum numbers is incorrect, we need to understand the rules governing quantum numbers. There are four quantum numbers: 1. **Principal Quantum Number (n)**: This can take positive integer values (n = 1, 2, 3,...). 2. **Azimuthal Quantum Number (l)**: This can take values from 0 to (n-1). For example, if n = 2, l can be 0 or 1. 3. **Magnetic Quantum Number (m_l)**: This can take values from -l to +l. For example, if l = 1, m_l can be -1, 0, or +1. 4. **Spin Quantum Number (m_s)**: This can take values of +1/2 or -1/2. Now, let's analyze the possible sets of quantum numbers to identify the incorrect one. ### Step-by-Step Solution: 1. **Identify the Sets of Quantum Numbers**: Review the given sets of quantum numbers. Each set should consist of four values: (n, l, m_l, m_s). 2. **Check Each Set Against the Rules**: - For each set, check if the values of l, m_l, and m_s comply with the rules based on the value of n. - Ensure that l is in the range of 0 to (n-1). - Ensure that m_l is in the range of -l to +l. - Ensure that m_s is either +1/2 or -1/2. 3. **Example Analysis**: - **Set 1**: (n=2, l=1, m_l=0, m_s=+1/2) - n = 2 → l can be 0 or 1 (valid) - l = 1 → m_l can be -1, 0, +1 (valid) - m_s = +1/2 (valid) - **Set 2**: (n=3, l=2, m_l=1, m_s=-1/2) - n = 3 → l can be 0, 1, or 2 (valid) - l = 2 → m_l can be -2, -1, 0, +1, +2 (valid) - m_s = -1/2 (valid) - **Set 3**: (n=3, l=3, m_l=0, m_s=+1/2) - n = 3 → l can be 0, 1, or 2 (invalid since l cannot equal n) - **Set 4**: (n=2, l=1, m_l=1, m_s=-1/2) - n = 2 → l can be 0 or 1 (valid) - l = 1 → m_l can be -1, 0, +1 (valid) - m_s = -1/2 (valid) 4. **Conclusion**: The incorrect set of quantum numbers is **Set 3**: (n=3, l=3, m_l=0, m_s=+1/2) because l cannot equal n. ### Final Answer: The incorrect set of quantum numbers is **(n=3, l=3, m_l=0, m_s=+1/2)**.
