Bohr Model ws

BOHR MODEL Name _______________________________ 1. Draw an energy level diagram for the first 5 energy levels in a hydrogen atom that is based on the Bohr model. 2. Calculate the energy for the n = 1 and the n = 2 level (orbits) for an electron in a hydrogen atom. 3. Describe what can happen when a hydrogen atom absorbs a photon of light, and when a photon of light is emitted from a hydrogen atom. 4. Calculate the energy difference between the n = 1 and the n = 4 levels in a hydrogen atom. What is the energy of a photon that would excite an electron from the n = 1 level to the n = 4 level? 5. Calculate the wavelength of a photon of light that would excite an electron in a hydrogen atom from the n = 1 to the n = 4 level. 6. Calculate the amount of energy required to ionize a hydrogen atom (remove the electron) when the electron is in the n = 1 level. 7. Which condition requires more energy to remove an electron: a. when an electron is close to the nucleus, or when an electron is further from the nucleus? Explain. b. when the nuclear charge is a + 1, or when the nuclear charge is a + 5 (assume the electron is the same distance from the nucleus)? Explain. Bohr Model
