(a) Although the helium atom is not H-like, use the Bohr formula for H-like helium anyway to estimate the ionization energy of helium. (b) The measured ionization energy of helium is 24.6 eV. Suppose that the difference between this number and the number you computed in part (a) comes entirely from the Coulomb repulsion between the two electrons. Use this assumption to estimate the average distance between the two electrons (in Angstroms) in helium’s 1s shell.

The Hamiltonian of the helium atom, under the assumption that the mass of the nucleus is much greater than that of the electrons and ignoring the spin, is of the form: Where are the position and momentum of the electron and is the atomic number of helium. Note that the first four terms are simply the sum of two Hamiltonians corresponding to a hydrogen atom for each electron; while the last term represents the interaction between both electrons. i) Investigate...

H-like atom: Bohr's model part 1 You carry out a theoretical work on absorption of alpha rays, passing on to a study of the structure of atoms on the basis of Rutherford's discovery of the atomic nucleus. By introducing conceptions borrowed from Quantum Theory established by Planck, you succeeded in working out and presenting a picture of atomic structure that, with later improvements, still fitly serves as an elucidation of the physical & chemical properties of the elements. You started...

INTRODUCTION The chemical and physical properties of substances are influenced by the way in which valence electrons are distributed and by the three-dimensional shape of the molecule or ion. X- ray and neutron diffraction, infrared, Raman and microwave absorption spectroscopy, as well as dipole moment measurements are used to ascertain the three-dimensional structure of a substance. Thus, techniques are available which can identify the geometry of substances. Results of these measurements generally...
