Suppose that you shine light of energy 1050 kJ/mol on an H in the ground state. What happens to the light and to the electron? The light is absorbed and the final energy of the electron is 328 kJ/mol R H . The light is not absorbed and the final energy of the electron is 1050 kJ/mol. The light is absorbed and the final energy of the electron is 1050 kJ/mol. Why are the energy levels of H and He+ different? By Coulomb s Law, the attraction between the nucleus and electron is stronger for He + . Why does Cl, in the ground state, exhibit absorption from n=1 to n=3?

Unformatted text preview: Cl has energetic valence electrons for which this transition is favorable. Why are all the energy values negative? The zero of energy is set as the electron and the nucleus dissociated completely. In an atom of any element, the 2s orbital is: only at lower energy than the 2p orbital for atoms with more than one electron. Why are the energy levels not equally spaced? The energies scale as 1/n 2 so they get closer together as n gets larger....
