WebNov 14, 2024 · Bohr's second postulate is then a way of implementing this idea. By requiring the angular momentum to be quantized, Bohr is saying that only certain orbits of the electron are allowed to take place. In particular, there is an orbit with a smallest amount of angular momentum (with angular momentum $\hbar$ ), and the electron cannot emit ...
