A triply ionized beryllium atom is in the ground state. It absorbs energy and makes a transition to the n = 5 excited state. The ion returns to the ground state by emitting FOUR photons ONLY. What is the wavelength of the second highest energy photon?

2. Consider a simplified model of a triply ionized beryllium-9 atom (Be): four protons plus five neutrons in the atom's nucleus, "orbited" by just one electron at a constant distance of 5.75 x 10m. (Note: This is not the actual distance, but it is the correct order-of-magnitude.) (6 pts.) You can solve (a) & (b) in either order. Label your work clearly a. What is the strength (magnitude) of the attractive electric force between the nucleus and the electron? Show...

4. When a hydrogen atom is bombarded, the atom may be raised into a higher energy state. As the excited electron falls back to the lower energy levels, light is emitted. What are the three longest-wavelength spectral lines emitted by the hydrogen atom as it returns to the n = 1 state from higher energy states? Give your answers to three significant figures. The lowest possible state, n = 1, corresponds to the electron in its smallest possible orbit; it...
Be3+ is a one-electron ion. It is a beryllium atom that has lost 3 of its electrons. Minimum energy of a photon that would ionize this ion= -217.6 eV The wavelength of the photon that would excite Be3+ from its ground state to its first excited state= 7.56 nm Calculate the kinetic energy of the photoelectrons if radiation of 4.0 nm of wavelength falls on an ensemble of Be3+ ions.
