Question

Which of the following set of quantum number is not possible in order of
n,l, $m_1$, $m_s$?

• A. 3 2 1 $+\frac{1}{2}$
• B. 3 2 1 $-\frac{1}{2}$
• C. 3 2 1 0
• D. 3 2 -1 $+\frac{1}{2}$

Answer 1

Answer: (C)

3 2 1 0

Spin quantum number $\left(m_s\right)$ value must be -1/2 or +1/2.It value cannot 0.
