Question

which of the following set of quantum numbers are not correct?
a.n=2 l=2m=0s=+1/2
b.n=1 l=0 m=0 s=-1/2
c.n=3 l=2 m=2 s=+1/2
d.n=4 l=3 m=-1 s=+1/2​

Answer 1

Answer:

a.

Explanation:

a.

for n = 2, the value of l will be n - 1 i.e, here l = 1, but given that l = 2, so (a) is the incorrect answer.
