Question

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

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

Answer 1

The correct option is A size,shape,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. It corresponds to the principal energy level to which the electron belongs.

Azimuthal quantum number denotes the subshell (orbital) to which the electron belongs and also determines the shape of the orbitals and energy assoiciated with the angular momentum of the electron.

Magnetic quantum number determines the preferred orientation of orbitals in space.
