Discussion Overview

The discussion revolves around the nature of electrons and protons, particularly focusing on their charge, size, and the implications of these properties. Participants explore theoretical and conceptual aspects of particle physics, including the structure of protons and the characteristics of electrons.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants note that electrons and protons have equal but opposite charges, despite the significant difference in their sizes.
  • Others suggest that the relationship between mass, size, and charge is not straightforward, indicating a lack of understanding about why these properties exist as they do.
  • A participant points out that protons are not fundamental particles like electrons, as they are composed of quarks, which have fractional charges.
  • There is mention of other charged particles beyond just protons and electrons, suggesting a broader context for understanding charge in particle physics.
  • One participant emphasizes that the concept of "width" for particles like electrons is complex and not directly related to their charge, hinting at deeper theoretical implications.

Areas of Agreement / Disagreement

The discussion remains unresolved, with participants expressing differing views on the relationship between charge, size, and mass of particles. There is no consensus on the underlying reasons for these properties.

Contextual Notes

Participants acknowledge limitations in current understanding, particularly regarding the nature of particle properties and the implications of theories like string theory. The discussion reflects ongoing uncertainties in the field.

In chemistry I remember learning that electrons and protons had equal but opposite charges but also that electrons were much smaller than protons. So how is it that something so much smaller can have an equal charge?

I don't think there is an answer to that other than "we don't know". It just seems to be that way. But did you know that there are several different particles of various masses that also have an electric charge of +1 or -1? It's not just the proton and electron.
 
Why not?

Anyway, a proton isn't a single thing like an electron. Protons are made of quarks so an electron and a proton aren't 'opposite' really.

For that, you have to look at the positron.
 
Well electrons have a width of zero as far as we know. Protons are made up of quarks which carry a charge of 1/3e or 2/3e and they are also infinitely thin. We don't know why they have those charges, but the width or mass of a particle doesn't have anything to do with it as far as we know. (Actually "width of zero" would need some explanation, but I don't feel like arguing over string theory, momentum independent interactions, or measurement limits)
 
Astro_Will,

You seem to think that mass and size are somehow related to charge. Where did you get that idea?
