  • question_answer
    Principal, azimuthal and magnetic quantum numbers are respectively related to

    A)  shape, size and orientation

    B)  size, shape and orientation

    C)  size, orientation and shape

    D)  none of these.

    Correct Answer: B

    Solution :

    Principle quantum number (n) represents the name, size and energy of the shell of the electron. \[n=1,2,3,4\] ....... Azimuthal quantum number (\[l\]) describes the spatial distribution of electron cloud and angular momentum. Magnetic quantum number (m) describes the possible orientations of orbitals.
