The strength of electromagnetism in an atom?

Click For Summary

Discussion Overview

The discussion revolves around the strength of electromagnetism in atoms, particularly in the context of hydrogen and its comparison to macroscopic systems. Participants explore how to conceptualize atomic interactions using everyday objects or scenarios.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that atoms are held together by "strong" electromagnetism and seeks to relate this energy to a known object.
  • Another participant counters that the energy required to remove an electron from a hydrogen atom is only 13.6 eV, which they argue is relatively small.
  • A third participant expresses uncertainty about their previous understanding of the strength of atomic interactions, indicating a potential misconception.
  • A fourth participant confirms the 13.6 eV value for hydrogen and notes that this energy is not easily relatable to macroscopic systems, suggesting that it is too small for meaningful comparison.
  • This participant proposes using the HCl molecule as an analogy, describing it as a harmonic oscillator with a Hooke's constant that could be compared to a macroscopic spring.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the characterization of electromagnetic strength in atoms, with differing views on the significance of the energy values discussed and the appropriateness of analogies to macroscopic objects.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about the strength of electromagnetism and the energy values, as well as the challenge of finding suitable macroscopic analogies for atomic interactions.

I realize atoms are held together by STRONG electromagnetism, but if you were to convert this energy into an everyday scenario, how strong would it really be? I'm trying to explain the power behind a small atom and I feel using a 'real', known object. Thank you in advance for any answers.

"Strong" electromagnetism? Why, the electron in a hydrogen atom only requires 13.6eV of energy to remove. I don't think that's a lot.
 
Oh? Hmm, interesting. Maybe I had something wrong somewhere.. but I had always thought that the power was which more than that.
 
Fightfish is right, the amount of energy needed to remove the electron of a neutral hydrogen atom is 13.6 eV. This energy isn't comparable to any energy of macroscopic system I know of; it's way too small so it would be hard to get a "feeling" making a comparison to a "real known object".

On the other hand, if you take the HCl molecule, you can think of it as roughly a harmonic oscilator whose Hooke's constant is of the order of 200 N/m (out of memory). So you can roughly think that the 2 atoms are linked via a spring whose Hooke's constant can be compared to a macroscopic spring, that would be your "real object".
