Azimuthal quantum number reflects the shape of the region in space an electron occupies. C. Pauli exclusion is the build-up of electron configuration in atom according to the energy diagram D.

49. Which of the following correctly identifies how Louis de Broglie's concept of the electron as a particle-wave helped to explain energy levels for an electron in an atom. A. de Broglie described the electron orbit as a circular standing wave pattern with a specific angular momentum as required by the Bohr hypothesis. B. de Broglie described the electron as a planar wave with a non- specific frequency as required by the Bohr hypothesis. C. de Broglie described the electron as a wave whose range of frequencies was continuous and thus allowed for all the possible electron energies predicted by Bohr. D. de Broglie described the electron as a spherical wave whose wavelength was dependent upon the speed with which it orbits the nucleus, as needed to explain the Bohr hypothesis.
