For the quantum numbers n = 3, l = 1, and m = 0, identify the corresponding orbital.

1. 3p
2. 3d
3. 3s
4. 4p

Correct answer: 3p

Solution

The principal quantum number n = 3 indicates the third shell, and the azimuthal quantum number l = 1 corresponds to a p-orbital. The magnetic quantum number m = 0 specifies one of the p-orbitals. Thus, the orbital is 3p.
