We're asked to** ****determine which set of quantum numbers cannot occur together **to

To solve this problem, let’s first define the values of the first three quantum numbers:

**•**** principal quantum number (n) ****→**energy level in orbitals and its value could be **any positive integer **starting from 1 to infinity

**•****angular momentum quantum number (**ℓ**) ****→ ****(l) has to be at least 1 less than n, **range of values from** 0 up to (n-1)**

**• ****magnetic quantum number (m**_{ℓ}**)****→ **range of values from **-ℓ to +ℓ.**

Which set of quantum numbers *cannot* occur together to specify an orbital?

a. *n*=3,*l*=-3,*m**l*=0

b. *n*=2,*l*=1,*m**l*=-1

c. *n*=3,*l*=1,*m**l*=-1

d. *n*=4,*l*=3,*m**l*=3
