- Thomson’s Experiment: J.J. Thomson’s experiments with cathode rays not only led to the discovery of the electron but also earned him the Nobel Prize in Physics in 1906. His work established the electron as a fundamental constituent of atoms.
- Bohr Model: Niels Bohr’s model of the atom, which introduced quantized electron orbits, was pivotal in explaining the hydrogen spectrum and set the stage for the development of quantum mechanics.
