Indicate which of the following sets of quantum numbers in an atom are unacceptable and explain why:

(a) $\left(1,0, \frac{1}{2}, \frac{1}{2}\right),(\mathrm{b})\left(3,0,0,+\frac{1}{2}\right),(\mathrm{c})\left(2,2,1,+\frac{1}{2}\right)$ (d) $\left(4,3,-2,+\frac{1}{2}\right),(\text { e })(3,2,1,1)$.
