Discussion Overview

The discussion revolves around the classification of neutrons and protons as particles, exploring the nature of charged and uncharged particles, and the implications of subatomic structures. It touches on theoretical concepts and definitions within particle physics.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants argue that if neutrons are composed of other charged particles, they should not be classified as particles themselves.
  • Others point out that neutrinos and certain gauge bosons are examples of uncharged particles, suggesting that charge is not a universal property of all particles.
  • One participant asserts that neutrons can be formed from the merging of an electron and a proton, but this does not imply they are made of other particles.
  • Another participant notes that neutrons and protons are composed of quarks, which are considered elementary particles, leading to confusion about the classification of neutrons and protons as particles.
  • There is a suggestion that all non-point particles may be considered as groups of other particles, raising questions about the definitions of particles in general.

Areas of Agreement / Disagreement

Participants express differing views on whether neutrons and protons should be classified as particles, with some asserting they are not elementary due to their quark composition, while others maintain that they are indeed particles despite this structure. The discussion remains unresolved.

Contextual Notes

There are limitations in the definitions of particles being discussed, particularly regarding the distinction between elementary and composite particles, as well as the implications of charge in particle classification.

If neutrons are made of other charged particles, neutrons are not particles. And I can't figure out any other particles without charge.. Is Electromagnetism a property of all particles?

Neutrinos are elementary particles that have no charge. Dark matter has no charge, so most matter has no charge.

Thanks.

This is not true.

While neutrons can be formed by the merging of an electron and a proton, they does not mean they are made of other particles. Subatomic particles are made of quarks. The type of quarks they have determines their charge. And they can change from one type to another.

Wait what? neutrons are particles? but I have always seen them described as three quarks orbiting each others? and protons to, so I tought they were just groups of quarks? and I assumed it to be like the atom, where the atom is not a particle because it is a group of particles. Aren't all particles that aren't point particles made of other particles?

Neutrons are particles, but they are not elementary particles, as they are made from other particles. Quarks are elementary particles since they have no known substructure.
