Explain giving reason, which of the following sets of quantum numbers

1.	Explain giving reason, which of the following sets of quantum numbers are not possible:(i) n = 1,l = 1,ml = 0, ms = \(+\frac{1}{2}\)(ii) n = 0,l = 2, ml = -2, ms = \(+\frac{1}{2}\)
Answer» (i) When n = 1, value of l cannot be equal to 1. Thus it is not possible. (ii) Value of n i.e., shell starts from 1 and not from zero. Thus, it is not possible.
