WebApr 6, 2024 · Later on, Louis de Broglie explained the postulate of the quantization of the angular momentum of an electron given by Bohr. He stated that an electron in motion shows the behavior of a particle-wave. Mathematically, Angular momentum = mvr or \[\frac{nh}{2\pi }\] Here,v = velocity. n = the orbit where electrons are present. m = mass … WebApr 6, 2024 · Hint: In accordance to de Broglie’s explanation of the second postulate of Bohr, there an assumption is created that the integral number of wavelengths should be equivalent to the circumference of circular …
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. Web4 Notes 2: Postulates ofQuantum Mechanics oven Ag µx µz − µx+i µz+i µz−i 50% 50% Fig. 1.

WebBohrs second postulate defines these stable orbits. This postulate states that the electron revolves around the nucleus only in those orbits for which the angular momentum is … WebSep 12, 2024 · The electron’s speed is largest in the first Bohr orbit, for n = 1, which is the orbit closest to the nucleus. The radius of the first Bohr orbit is called the Bohr radius of hydrogen, denoted as a0. Its value is obtained by setting n = 1 in Equation 6.5.6: a0 = 4πϵ0 ℏ2 mee2 = 5.29 × 10 − 11m = 0.529 Å.
