Explore atomic structure by tracing four important atomic models and their improvements from the early theory. Examine emission lines, quantum theory, the photoelectric effect, and electronic and spatial configurations.
This lecture traces the development of atomic structure and subatomic particles. It explains Thomson's cathode ray experiment revealing the electron and Millikan's measurements of charge and mass.
Trace Thomson's plum pudding model to the nuclear model via scattering experiments that reveal a positive nucleus and electrons. Link this to atomic number, mass number, isotopes, and isobars.
Explore the nature of electromagnetic radiation, its spectrum, and the energy-frequency relation. Learn about black body radiation, the photoelectric effect, and atomic emission and absorption spectra, including hydrogen.
Explore Bohr's atomic model with quantized electron orbits and energy levels, linking transitions to hydrogen line spectra, and discuss its limitations for magnetic splitting and bonding.
Explore the quantum mechanical model of atomic structure, covering de Broglie wavelength, Heisenberg uncertainty principle, wave function, and the probability of finding electrons using quantum numbers n, l, m, s.
Explore the quantum mechanics of atoms, the Aufbau filling order and electronic configuration, Pauli exclusion principle, and how half-filled and fully filled configurations yield greater stability.
