What is the maximum number of orbitals that can be identified with the following quantum numbers? n = 3, l = 1, mₗ = 0

1. 1
2. 2
3. 3
4. 4

Correct answer: 1

Solution

The quantum numbers specify a single orbital. For n = 3 and l = 1, the subshell is 3p. The magnetic quantum number mₗ = 0 corresponds to one specific orbital within the 3p subshell. Thus, only one orbital is identified.
