Each set of quantum numbers is supposed to specify an orbital. However, each set contains one quantum number that is not allowed. Replace the quantum number that is not allowed with one that is allowed.

n=3;l=3;ml=+2


a. ml=0
b. n=4
c. l=4
d. n=2

Final answer:

The not allowed quantum number ml=+2 in the set n=3, l=3, and ml=+2 should be replaced with ml=0.

Step-by-step explanation:

The set of quantum numbers mentioned in option a, n=3, l=3, and ml=+2, contains one quantum number that is not allowed, which is ml=+2. The ml quantum number represents the magnetic quantum number and it specifies the orientation of the orbital in space. The ml value must range from -l to +l, so for l=3, the allowed values of ml would be -3,-2,-1,0,1,2,3. Therefore, to replace the quantum number that is not allowed, we can use any value of ml from the allowed range, such as ml=0 or ml=1.

Thus, the correct replacement for the not allowed quantum number ml=+2 in the set n=3, l=3, and ml=+2 is ml=0 (option a).
