What is Bohr postulate of angular momentum?

According to Bohr’s atomic model, the angular momentum of electrons orbiting around the nucleus is quantized. He further added that electrons move only in those orbits where the angular momentum of an electron is an integral multiple of h/2.

How Bohr’s atomic model was explained by de Broglie explain?

De Broglie’s Justification of Bohr’s Assumption De Broglie realized that if you use the wavelength associated with the electron, and assume that an integral number of wavelengths must fit in the circumference of an orbit, you get the same quantized angular momenta that Bohr did.

Why did Bohr Quantise angular momentum?

Therefore, quantising angular momentum allows for the electron wave to not interfere with itself during orbit.

Which one of the following statements is the assumption that Niels Bohr made about the angular momentum of the electron in the hydrogen atom?

Question: Which one of the following statements is the assumption that Niels Bohr made about the angular momentum of the electron in the hydrogen atom? The angular momentum is not quantized.

What are the main postulates of Bohr’s atomic theory?

Bohr’s model of the hydrogen atom is based on three postulates: (1) an electron moves around the nucleus in a circular orbit, (2) an electron’s angular momentum in the orbit is quantized, and (3) the change in an electron’s energy as it makes a quantum jump from one orbit to another is always accompanied by the …

How did de Broglie explain the Bohr’s second postulate of Quantisation Explain with suitable diagram?

De-Broglie’s hypothesis that electron has a wavelength λ = h/mv gave an explanation for Bohr’s quantised orbits by bringing in the wave particle duality. Orbits correspond to circular standing waves in which the circumference of the orbits equal whole number of wavelength.

What do you mean by quantization of angular momentum?

Quantization of angular momentum means that the radius of the orbit and the energy will be quantized as well. Bohr assumed that the discrete lines seen in the spectrum of the hydrogen atom were due to transitions of an electron from one allowed orbit/energy to another.

How did Niels Bohr explain energy levels?

With his model, Bohr explained how electrons could jump from one orbit to another only by emitting or absorbing energy in fixed quanta. For example, if an electron jumps one orbit closer to the nucleus, it must emit energy equal to the difference of the energies of the two orbits.

Which of the following is not an assumption made regarding Bohrs atomic model?

According to Bohr’s model, when does an electron emit electromagnetic radiation? Which of the following is NOT an assumption made regarding Bohr’s atomic model? The electron is continuously emitting electromagnetic radiation. An electron will emit or absorb a photon if moved to a different orbit.

Which one of the following statements was assumed by Bohr in developing his atomic theory?

Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii.
