Question

Consider the following sets of quantum numbers.
$\begin{array}{ccccc}& & & & \\ & n& l& m_1& m_s\\ \left(i\right)& 3& 1& -2& -\frac{1}{2}\\ \left(ii\right)& 2& 1& 0& +\frac{1}{2}\\ \left(iii\right)& 4& 2& -1& -\frac{1}{2}\\ \left(iv\right)& 3& 2& 0& +\frac{1}{2}\\ \left(v\right)& 2& 0& +1& -\frac{1}{2}\end{array}$
Which of the following set of quantum numbers is possible

• A. (i), (v), (ii), (iv)
• B. (ii), (iii), (iv), (v)
• C. (i), (v), (iii)
• D. (ii), (iii), (iv)

Answer 1

The correct option is D (ii), (iii), (iv)

If l = 1, $m_l$ = – 1, 0, +1
If l = 0, $m_l$ = 0
