How does the quantum model justify accelerating electrons not losing energy?

Click For Summary

Discussion Overview

The discussion revolves around the question of how the quantum model of the atom accounts for electrons not losing energy while accelerating, a concern raised regarding classical and Bohr models. Participants explore the implications of quantum mechanics on atomic behavior, particularly in relation to electromagnetic radiation (EMR) and the stability of electron orbits.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants highlight a flaw in the classical and Bohr models, suggesting that they imply electrons should lose energy as they accelerate around the nucleus.
  • Others argue that in quantum mechanics, the concept of acceleration in the ground state is not applicable, as it is a stationary state.
  • One participant mentions that the stability of electron orbits in the Bohr model is due to the condition that the orbital circumference must be an integer multiple of the electron's wavelength.
  • Another perspective suggests that quantum mechanics involves complex interactions with the electromagnetic field, leading to transitions between energy states that can involve photon emission.
  • Some participants express confusion about the implications of quantum mechanics, questioning how electrons can be considered to emit EMR while maintaining stable orbits.
  • There are references to scattering experiments that show different results based on the electron cloud's size and behavior, indicating a nuanced understanding of atomic interactions.
  • One participant emphasizes that the electron's behavior in quantum mechanics is difficult to visualize and challenges the notion of treating electrons as point-like particles.

Areas of Agreement / Disagreement

The discussion reflects multiple competing views regarding the interpretation of quantum mechanics and its implications for electron behavior. There is no consensus on how to reconcile the classical expectations of energy loss with the quantum model's predictions.

Contextual Notes

Participants note limitations in understanding quantum mechanics, including the challenges of visualizing atomic behavior and the dependence on specific models. The discussion also highlights the unresolved nature of certain theoretical aspects and the need for further exploration in the field.

Who May Find This Useful

This discussion may be of interest to students and enthusiasts of quantum mechanics, physics educators, and researchers exploring atomic theory and the implications of quantum behavior on classical models.

A spinor describing an electron needs to be spatially rotated by 4 Pi. So? They're not three-dimensional objects.

In short: You don't understand quantum mechanics.

I think you should study more about quantum mechanics.

Spinor is three-dimensional objects. (But I do not believe spin, so this is not my opinion.)

Because One experiment in 1975 showed that the spinning neutrons return to their original configuration when they are rotated by an angle of 4π (not 2π) .
(H.Rauch et al., Phys.Lett. 54A(1975) 425)

But I think this is caused by the fact that netron g factor is -3.826. The spin angular momentum is 1/2 hbar, So this g-factor is twice the value which I expect(-1.913). I think the angular momentum is hbar.
1/2 is based on the Shrodinger equation which I do not believe.
