In the picture are two diagrams of the first five orbits in the Bohr model labeled A - E. The dot in an orbit is the electron. The nucleus is not shown. Shown is a BEFORE and AFTER state of the atom. An energy level diagram for the Bohr hydrogen atom is shown. Which of these events has occurred in going from the BEFORE to the AFTER state?         a. a photon of energy 0.97 eV has been emitted   b. a photon of energy 1.51 eV has been absorbed   c. a photon of energy 1.51 eV has been emitted   d. an electron of energy 1.51 eV has been emitted   e. a photon of energy 0.97 eV has been absorbed

An electron is orbiting in the n = 3 orbit of an hydrogen atom. It is promoted by absorption of light energy to the n = 4 level. The Rydberg constant is R = 1.097 x 107 m-1. What is the wavelength of the light absorbed? Select one: a. 427 nm b. 1.094 μm c. 1.875 μm d. 763 nm

The Balmer series in hydrogen includes the Paschen series. has four lines in the ultraviolet. O includes both the Paschen series and the Lyman series. O has four lines in the visible. O includes the Lyman series.

In the ground state of the Hydrogen atom the energy of the electron is E0 = -13.61 eV. What is the energy of the electron in the ground state of the He+ ion?  Hints:The He+ ion is a Hydrogen-like structure, it has only one electron.How does the energy of the electron depend on the charge of the nucleus? Is this a bound state? Make sure, your answer has the correct sign.   Incorrect.
