Which quantum number determines the spatial orientation of an atomic orbital in space?
Answer and explanation
Correct answer: C. Magnetic quantum number ()
- Step 1: The principal quantum number dictates orbital size and energy shell; dictates orbital geometric shape ().
- Step 2: The magnetic quantum number specifies the spatial orientation of the orbital along Cartesian axes ().
Answer
Magnetic quantum number ().
Why not the others: 'Principal ' defines energy level and shell distance; 'Angular momentum ' defines subshell geometric shape; 'Spin ' specifies the intrinsic angular momentum of the electron.
