CHEMISTRY 121 1 Department of Chemistry University of British Columbia Problem Set 13 Interaction of Light with Matter 1. What is the energy (in J) of the 3 p z state in the hydrogen atom? 2. What is the wavelength (in nm) of light emitted when the electron in a hydrogen atom moves from the 5 p orbital to the 2 s orbital? 3. The first ionization energy of cesium is 382 kJ/mol. Calculate the minimum frequency of light (in Hz) required to ionize gas phase cesium atoms in their ground electronic state. 4. He + ions are excited to the 4 s state. These ions decay to lower energy states by one or more allowed transitions, emitting light in the process. List all these possible allowed transitions, indicating the orbitals involved (for example, a transition from the 6s to the 5p orbital would be specified as 6 s 5 p , rather than 6 5). Which of these allowed transitions will produce the most energetic photons. 5.
