Which quantum number specifies the orientation of an electron cloud in space and determines the subshell's spatial degeneracy?
A. Principal quantum number
B. Azimuthal quantum number
C. Magnetic quantum number✓ Correct Answer
D. Spin quantum number
💡 Solution & Explanation
The magnetic quantum number determines the orientation of an atomic orbital within a spatial region and defines the subshell degeneracy under external fields. The principal quantum number governs overall energy levels, whereas the azimuthal number determines orbital shape. Atomic structure principles form the foundation of general science questions.
