Where the Electrons Are: Configurations and Photoelectron Spectroscopy
Nobody has seen an electron shell, yet a photoelectron spectrum shows them as cleanly as rungs on a ladder. Knock electrons out with light and count how much energy each one cost.

By the end
- 01Write ground-state electron configurations of atoms and ions by the aufbau order
- 02Estimate relative ionization energies from distance and shielded nuclear charge with Coulomb's law
- 03Read a photoelectron spectrum peak's position as binding energy and its height as electron count
- 04Match a photoelectron spectrum to an atom's configuration and vice versa
