Why Bohr s theory is a semi classical quantum theory

Bohr's Theory: A theory about the structure of atoms.

Neng's explanation.

And so it goes. Northern Qi Yan Zhitui "Yan's Family Motto and Miscellaneous Arts": Wang Su, Ge Hong, Tao Kan's disciples, not allowed to look at the hands, this and diligent ambition.

It's better to be able to do it. Tang Wang Jiyou's poem "Viewing the Landscape of the Mural Landscape of the Sheren": "Yu Gong laughed and said to Yu, the younger brother Danqing can be defeated by Jane?

One of Song Chen Shidao's "Quatrains": "A few trees are straight and green and can be thin, and a remnant photo is left for whom." ”

Words decomposition can explain ability é ability , ability , ability . Skill.

Talent. Talented: capable people.

Expert. Meritocracy. Skilled craftsman .

Those who can are teachers. Competent, good at: Able.

It can be soft and rigid. As far as you can. Cannot help doing something.

Active. Yes (indicates possibility): The little brother can walk.

Should: You can't say so much about your explanation of your (er) ě your: your father.

Generations. Erru (you and I are commensurate, close relationship). Ercao (you people).

Double-cross each other. So: Occasionally.

But Erl. That, its (refers to time): time.

Then. That's it, it's just (also called "ear"): the anger of the cloth is also free from the crown to stop the trembling.

Bohr's theory, a theory about the structure of the atom. It was proposed by Bohr in 1913. It was built on the basis of the Rutherford atomic model with Planck's quantum concept.

Bohr postulated that the extranuclear electrons of the hydrogen atom have a definite, unchanging energy as they orbit and do not release energy, and this state is known as a stationary state. The stationary state with the lowest energy is called the ground state; A stationary state with an energy higher than the ground state is called an excited state. According to classical mechanics, electrons operate in the positive electric field of the nucleus and should constantly release energy before falling into the nucleus.

If this is the case, the atom will be destroyed and the objective world will cease to exist. Thus, Bohr's steady-state assumption is necessary to explain that atoms are capable of stable existence.

The theory itself is still based on the classical theory, and its theory contradicts the classical theory. It can only interpret the spectra of hydrogen atoms and hydrogen-like atoms (such as lithium + ions, etc.), and it encounters difficulties in solving the spectra of other atoms, such as when applying the theory to other atoms, the theoretical results do not match the experiment, and the intensity of the spectral lines and the width between adjacent spectral lines cannot be calculated. These defects are mainly caused by the imposition of the laws of classical mechanics on microscopic particles (e.g., orbital concept) by treating microscopic particles (electrons, atoms, etc.) as particles in classical mechanics.

The proposal of "Bohr's theory" broke the situation of classical physics dominating the world, opened up the prospect of revealing the basic characteristics of the microscopic world, and laid the foundation for the quantum theory system.

Bohr's Theory: A theory about the structure of atoms.

The two are incompatible, each seizing on the other's weaknesses to defend its own theories. However, quantum mechanics has made amazing progress, and Bohr's conception of "composite particles forming atomic nuclei" has provided a strong theoretical basis for the realization of atomic nuclear fission.

The theory of quantum mechanics is correct.

Albert Einstein repeatedly pointed out that the existing theories of quantum mechanics are inconsistent, or at least incomplete, but they were all cracked by its founder, Bohr.

Einstein first realized that one of the two pillars of quantum mechanics - the uncertain relationship may be problematic, so he designed the "Einstein light box" to prove that energy and time (or momentum and displacement) can be measured at the same time. Einstein had no choice but to admit that the uncertain relationship was correct.

Later, Eistan tried to use the "EPR-like fallacy" to show that the theory of quantum mechanics was incomplete, but it was "explained" by the Copenhagen School, although this explanation was not satisfactory.

In short, after 30 years of polemics between Einstein and Bohr, quantum mechanics has stood the test of time, and to this day, we cannot deny its correctness.

It seems that quantum mechanics refers to the microscopic, while relativity refers to the macroscopic, and there is no real right or wrong, just like the wave-particle duality of light!

1. The Bohr-Sommerfeld quantization condition is that when the quantum number n, the quantized energy level will tend to the classical version of the continuous energy, and the quantization weight theory will tend to the classical theory.

2. The Sommerfeld number is often represented by Greek letters. The Sommerfeld number is the ratio of the velocity of the electron in the first Bohr orbit to the velocity of the light in the vacuum, and is calculated as =E2 (4 0C) (where e is the charge of the electron, 0 is the vacuum dielectric constant, is the reduced Planck constant, and c is the speed of light in a vacuum).
