About This Topic

Students will learn about discrete energy levels in isolated atoms and the origin of emission and absorption line spectra. The production of X-rays will also be introduced.

Key Questions

  1. How do atomic energy levels explain emission and absorption line spectra?
  2. What is the difference between continuous and characteristic X-ray spectra?
  3. How can we calculate the energy of a photon emitted or absorbed during an electron transition?
