Among the following sets of quantum number, state which are possible. Explain why the other are not permitted?
(a) n=1, l=0, m=-1, `s=+1/2`
(b) n=, l=0, m=0, `s=-1/2`
(c ) `n=2, l=3, m=0, s=-1/2`
(c ) `n=2, l=3, m=0, s=+1/2`
(d) `n=3, l=1, m=1, s=-1/2`
(e ) `n=0, l=0, m=0, s=+1/2`
(f ) `n=2, l=0, m=0, s=-1/2`

Explanation

(a) This set is not possible because when l=0, m cannot have value -1
(b) Possible.
(c ) Not possible because l cannot have a value equal to 3 when n=2.
(d) Possible.
(e ) Not possible because n can never have a value equal to 0.
(f ) Possible.
