WebWith A. Sommerfeld’s extension of the Bohr theory in 1915–1916, it was turned into a powerful tool of atomic research and adopted and further developed by German physicists in particular. The new and more general Bohr–Sommerfeld theory described the atom in terms of two quantum numbers, while Bohr had originally used only one quantum number. Web14 de dez. de 2024 · The Rutherford atomic model was the first model to propose electrons as subatomic particles spinning around a central nucleus. It was revolutionary, but flawed.
