From the following sets of quantum numbers, state which are possible. Explain why the others are not possible.
(a) `n=0, l=0, m_(l)=0, s=+1//2` , (ii) ` n=1, l=0, m_(l)=0, s=-1//2`
(iii) ` n=1, l=1, m_(1)=0, s=+1//2` , (iv) `n=1, l=0, m_(l)=+1, s=+1//2`

Text Solution

Verified by Experts

(i) The set of quantum numbers in not possible because the minimum value of n can be 1 and not zero.
(ii) The set of quantum numbers is possible.
(iii) The set of quantum numbers is not possible because for `n=1, l` cannot be equal to 1. It can have 0 value.
(iv) The set of quantum numbers is not possible because for `l=0,m` cannot be +1 . It must be zero.
