Which one of the following sets of quantum numbers is possible ?

Options

A. `n=3, l=3, m, =-3, m_(s) =+(1)/(2)`
B. `n=2, l=1, m_(t) =2, m_(s) =-(1)/(2)`
C. `n=2, l=0, m_(i) =0, m_(s) =+(1)/(2)`
D. `n=1, l=0, m_(i)=0, m_(s)=0`

Answer

C

Explanation

A) For n = 3, value of l and n cannot be the same `therefore l ne 3`
B) For `l=1, m_(1) ne 2" as "m_(1) gt l_(1)` is not possible
C) `n=2, l=0, m_(l)=0, m_(s)=+(1)/(2)` is a possible set
D) `m_(s) =0` is incorrect.
