Bohrs 2nd postulate
WebMar 29, 2024 · I am reading how de Broglie justified the 2nd postulate of Niels Bohr (i.e. angular momentum of an electron to be integral multiple of $\frac{h}{2\pi}$).I get his explanation of electron acting like standing wave and circumference should hold integral multiples of wavelengths. WebApr 5, 2024 · Bohr combined classical and early quantum mechanics concepts to propose a three-postulate theory. These postulates are: 1. An electron in an atom revolves in certain stable orbits without emitting radiant energy. Each atom has certain definite stable orbits. Electrons can exist in these orbits.
