Question

What? If anything, is wrong with the following sets of quantum numbers.

a. n = 2, l = 2, ml = 0, ms = +1/2

b. n = 0, l = 0, ml = 0, ms = -1/2

c. n = 3, l = 2, ml = -2, ms = +1/2

d. n = 4, l = 2, ml = 2, ms = -1/2

Answer 1

a. l must be 0, 1, etc, to a maximum of n-1; therefore, since n = 2, l may not be larger than 1.

b. n must be an integer beginning at 1. It may not be zero.

I don't see anything wrong with c or d.

Answer 2

4,2,-1,1/2
