Stern-Gerlach Experiment and spin quantum number : Revealing Electron Spin
The Stern-Gerlach experiment, which took place in 1922, was the most important proof that electrons have spin and that they have a spin quantum number. A stream of silver atoms was sent through an experiment using a magnetic field that...

De Broglie vs Bohr: A Quantum Debate
Niels Bohr's model of the atom introduced the idea of quantised orbits for electrons. In these, electrons occupy stable energy levels and either give off or take in photons when they move between these levels. This model was able to...
