  1. IB1 ChemistryAtomic Structure 32.3 Emission spectra

  2. Clues to electronic structure • periodicity of elements • emission spectra • ionization energies

  3. Electromagnetic spectrum c = f λ where c is the speed of light, f is the frequency and λ is the wavelength

  4. Flame tests

  5. Dispersion

  6. Producing emission and absorption spectra Image: http://aplusphysics.com/wordpress/regents/tag/emission-spectra/

  7. Hydrogen emission spectrum red 656nm, blue 486nm, indigo 434nm, 410nm violet 397nm convergence at 365nm

  8. Emission spectra energy emitted as photons when electrons move between energy levels hf

  9. Atomic energy levels in hydrogen principal quantum number, n shells ground state ionization energy

  10. Sodium emission spectrum Line at 569nm whenelectrons in thirdshell are excited and then fall back givingoff a photon of visible light

  11. Ionization energy
