Question

Principal, azimuthal and magnetic quantum number respectively are related to :

• A. size, shape and orientation
• B. shape, size and orientation
• C. size, orientation and shape
• D. None of the above

Answer 1

The correct option is A size, shape and orientation

Principal, azimuthal and magnetic quantum numbers are respectively related to size, shape and orientation.
Principal quantum number gives the average distance of the electron from the nucleus.
Azimuthal quantum number denotes the subshell to which the electron belongs and the shape of the orbital Magnetic quantum number determines the orientations of orbitals in space.
