Electronic Structure and Periodic Properties (Chemistry)

Recall cards on the electronic structure of atoms and periodic trends: electromagnetic energy (wavelength, frequency, the speed of light, blackbody radiation, quantization, photons, the photoelectric effect, line spectra, the Rydberg formula, and wave-particle duality); the Bohr model of hydrogen (stationary states, quantized orbital energies, ground and excited states, the Bohr radius, and ionization); the development of quantum theory (de Broglie wavelength, the Heisenberg uncertainty principle, wavefunctions and atomic orbitals, the four quantum numbers, the Pauli exclusion principle, and orbital shapes); electron configurations (the Aufbau principle, Hund's rule, subshell filling order, valence and core electrons, noble gas notation, ion configurations, and the periodic table blocks); and periodic variations (atomic and ionic radii, effective nuclear charge, ionization energy, electron affinity, and metallic character).
