By the end you'll be able to

  1. Describe how solving Schrödinger's equation for an electron in the proton's Coulomb potential produces the energies Eₙ = −13.6 eV/n² and three quantum numbers
  2. State the allowed values of n, l, mₗ and mₛ, and use them to list and count the states of any level, including the n² and 2n² degeneracies
  3. Name the s, p, d and f orbitals, describe their shapes, and count their radial and angular nodes
  4. Interpret an orbital as a probability cloud rather than a path or a container, and show that the 1s electron's most probable distance is the Bohr radius, 0.0529 nm
  5. Explain how fine structure and the Zeeman effect exposed relativity and electron spin, and calculate a simple Zeeman splitting
  6. Connect hydrogen's shells and subshells to the structure of the periodic table
