Exercises

This closing exercise set works through the full sweep of the chapter — from counting electrons, protons and neutrons in a given species, through the wave/particle calculations on photons and the photoelectric effect, to the hydrogen line spectrum, Bohr's energy-level formula, de Broglie wavelengths, the Heisenberg uncertainty principle, and finally writing out quantum numbers and electronic configurations for real elements and ions. Work through them to check whether you can actually apply the formulas and pri …
