Bohrs 2nd postulate
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. WebBohr’s second postulate: The radius of the orbit of an electron can only take certain fixed values such that the angular momentum of the electron in these orbits is an integral …

WebBohr’s Atomic Model Second Postulate: Electrons must have the same number of “orthogonal” (equal) energy levels. The fixed nature of the orbits, which is the center postulate, is a progressive modification of Bohr’s original model. Bohr thought that the electrons could not be fixed in their orbits in his original model. WebDe Broglie's Justification of Bohr's Assumption. De Broglie came up with an explanation for why the angular momentum might be quantized in the manner Bohr assumed it was. De …
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. WebOct 2, 2024 · De - Broglie interprets Bohr's 2nd postulate in terms of wave nature of the electron. Hence, a circular orbit can be taken to be a stationary energy state only if it contains an integral number of de-Broglie wavelengths. Mathematically it is given as.
