Which of the following quantum numbers describes the orientation of an orbital in space relative to an external magnetic field?
A. Principal quantum number
B. Azimuthal quantum number
C. Magnetic quantum number✓ Correct Answer
D. Spin quantum number
💡 Solution & Explanation
The magnetic quantum number designates the specific spatial orientation of an atomic orbital within a given subshell when exposed to an external magnetic field. The principal quantum number determines the main energy level, whereas the azimuthal quantum number defines the orbital shape. Quantum numbers are fundamental concepts in physical chemistry necessary for understanding electron configurations and periodic table trends.
