Question

Out of the following pairs of electrons, identify the pairs of electrons present in degenerate orbitals.

• A. (a)$n=4,l=1,m_l=1,m_s=\frac{+1}{2}$
  (b)$n=3,l=2,m_l=1,m_s=\frac{+1}{2}$
• B. (a) $n=3,l=1,m_l=-1,m_s=\frac{+1}{2}$
  (b)$n=3,l=2,m_l=1,m_s=\frac{+1}{2}$
• C. (a)$n=3,l=2,m_l=+2,m_s=\frac{-1}{2}$
  (b)$n=3,l=2,m_l=+2,m_s=\frac{+1}{2}$
• D. (a) $n=3,l=2,m_l=-2,m_s=\frac{-1}{2}$
  (b) $n=3,l=2,m_l=-1,m_s=\frac{-1}{2}$
