Consider the following pair of electrons :
1. n = 3,l = 1, ml = 1, \(\rm m_s=+\frac{1}{2}\) and n = 3, l = 2, ml = 1, \(\rm m_s=+\frac{1}{2}\)
2. n = 3, l = 2, ml = -2, \(\rm m_s=-\frac{1}{2}\) and n = 3, l = 2, ml = 1, \(\rm m_s=-\frac{1}{2}\)
3. n = 3, l = 2, ml = 2, \(\rm m_s=+\frac{1}{2}\) and n = 4, l = 2, ml = 2, \(\rm m_s=+\frac{1}{2}\)
The pair of electrons present in degenerate orbitals is/are
1
Only 1
2
Only 2
3
Only 3
4
Only 2 and 3
