      Shapes of orbitals were explained by magnetic or azimuthal quantum number? Answer below the question is given magnetic quantum number but in the explanation video of this question answer is given azimuthal quantum number.

      1. Umair Ali khan

        Azimuthal. The discussion has correct answers. Please mention the question number, therefore, it is corrected.
