O When a hydrogen atom absorbs energy, as it does when an electric discharge passes through it, the electron stays in the orbit having n = 1. O The energy released when an electron drops from a higher to lower orbit appears as a photon with the appropriate frequency. O The energy released when an electron drops from a higher to lower orbit appears as a photon with energy equal to the energy difference between the two orbits. O Electrons are found in orbits of arbitrary energy. O The energy released when an electron drops from a higher to lower orbit appears as a photon with an arbitrary frequency. O Electron moves around the nucleus along orbits. O When a hydrogen atom absorbs energy, as it does when an electric discharge passes through it, the electron is raised from the orbit having n = 1 to a higher orbit, to n = 2 or n = 3 or even higher.

The energy E of the electron in a hydrogen atom can be calculated from the Bohr formula: E=-Ry/n2 In this equation Ry stands for the Rydberg energy, and n stands for the principal quantum number of the orbital that holds the electron. Calculate the wavelength of the line in the absorption line spectrum of hydrogen caused by the transition of the electron from an orbital with n=3 to an orbital with n=4.
The Balmer series provided the clue to the structure of the hydrogen atom, the simplest atom with only one electron. From that we learned about the structure of all atoms, even those more complex than uranium with its 92 electrons, the heaviest of the natural elements. This series ends on the lowest energy state with n=2 and starts with any state above it. The first line of the Balmer series arises when the atom changes from a state with n=3 to one with n=2. The second line comes from the change from n=4 to n=2, and so on. 3. Suppose that you could measure accurately the wavelengths of the first two lines of the Balmer series. How could you use those measurements to predict the wavelength of the first line of the Paschen series, the ones ending on n=3? This is the method by which we measure the energy levels of atoms experimentally.

The wavelength of the light emitted when the electron returns to the ground state from n=3 is the same as the wavelength of light absorbed to go from n=1 to n=3.3. the electron is farther from the nucleus on average in the n=3 state than in the ground state.4. The first excited state corresponds to n=3.5.

Bohr’s model of the atom is a system consisting of a small, dense nucleus surrounded by orbiting electrons. How does Bohr’s model explain spectral emission lines? Bohr developed a formula (shown below) that predicted the wavelength of a photon given off when an electron moves from one orbit to another orbit. His formula worked well to explain spectral emission lines in the hydrogen atom. Calculate the wavelength of light that would be emitted for the orbital transition of n = 7 to n = 1.
