Emission spectra and electron configuration

A structured lesson shell for electromagnetic radiation, spectra, quantized levels, orbitals, and ionization evidence.

Lesson progress
Relate wavelength, frequency, and photon energy.Explain why line spectra are discrete.Use ionization-energy evidence to infer electron structure.

Electron configuration connects observable spectra to the arrangement of electrons in energy levels and sublevels.

Photon energy
E = hf
Wave relationship
c = f\lambda
Worked example

Interpreting a convergence limit

  1. Find the energy of one photon using E = hf.
  2. Scale the value to one mole using Avogadro's constant.
  3. Convert joules per mole to kilojoules per mole.
