Is the following set of quantum numbers possible for a hydrogen atom? If not, correct it.
n = 4, l = 0, m _l = +1, m _s = -1/2

• A. The set of n = 4, l = 0, m_l = +1, m_s = -1/2 are possible for a hydrogen atom
• B. The set is not possible. It should be n = 4, l = 4, m_l = +1, m_s = -1/2
• C. The set is not possible. It should be n = 4, l = 4, m_l = +4, m_s = -1/2
• D. The set is not possible. It should be n = 4, l = 0, m_l = 0, m_s = -1/2
• E. The set is not possible. It should be n = 4, l = 0, m_l = +1, m_s =+1/2

Answer: (D)
