compute the ionization energy for a single atom of hydrogen and what wavelength of light corresponds to this energy?

Write the condensed ground-state electron configuration for the element P

This question relates to the energies of electrons in multielectron atoms. a) Can energies of electrons in multielectron atoms be determined exactly? Why or why not? b) Briefly describe the main idea of the variational principle and how it is used in the variational method.

Write four quantum numbers to describe the highest energy electron in the potassium atom. Be sure to include the four symbols and four correct numbers.

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.
