     The quantum number m of a free gaseous atom is associated with :

    A)  the effective volume of the orbital

    B)  the shape of the orbital

    C)  the spatial orientation of the orbital

    D)  the energy of the orbital in the absence of a magnetic field

    Correct Answer: C

    Solution :

    Magnetic quantum number m is associated with spatial orientation of the orbital. Principal quantum number (n) determines energy of the electron and size (volume) of the atom. Angular or azimuthal quantum number (l) determines shape of the orbital.
