    Bohr Bohr model Model
Click For Summary

Discussion Overview

The discussion revolves around the Bohr model of the atom, specifically addressing the question of how it prevents electron energy loss, which was a significant issue in earlier atomic models like Rutherford's. Participants explore the implications of quantized orbits and the nature of electron behavior in these orbits, touching on theoretical and conceptual aspects.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants note that Bohr's model introduced quantized orbiting radii for electrons, which supposedly prevents energy loss that would lead to electrons spiraling into the nucleus.
  • Others argue that the notion of electrons in fixed orbits is a fundamental error in Bohr's model, suggesting that electrons are better described as being smeared throughout a shell rather than occupying specific points.
  • A participant expresses confusion regarding atomic theory models and seeks clarification on the original question about energy loss.
  • It is mentioned that Bohr postulated electrons do not radiate energy while in discrete "Bohr orbits," but there is acknowledgment that he lacked a classical explanation for this behavior.

Areas of Agreement / Disagreement

Participants do not reach a consensus. There are competing views regarding the validity of the Bohr model's assumptions about electron behavior and energy loss, with some supporting its quantized nature and others challenging the concept of fixed orbits.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about electron behavior, the definitions of orbits versus electron distributions, and the unresolved nature of classical electrodynamics in relation to the Bohr model.

Even though Bohr's model is defunct, one important element of it survived, namely the strictly quantized orbiting radii of electrons. Supposedly this mended the gaping flaw of Rutherford's model in that it predicted that electrons would no longer lose energy to photon emission thereby causing them to spiral in their nucleus and all that well-known stuff. My question is how? How does limiting the possible orbits of an electron to specified energy levels in any way prevent energy loss from leading to the downfall of everything?

:confused: That it puts electrons in orbits is the main error in Bohr's model.

The energy levels remained, but electrons are smeared throughout the entire shell, rather than occupying a single point and orbiting around.
 
I'm getting my atomic theory models all mixed up! I appreciate the clarification, but it does not answer the actual question.
 
Bohr basically postulated that the electrons don't radiate when they are in one of the discrete "Bohr orbits." As far as I know, he didn't have an explanation for why they don't radiate as classical electrodynamics predicts they should.

O.o? That's interesting. Thank you for [somewhat] clarifying the matter.
