SUMMARY

Neutrons are classified as composite particles, which means they possess a non-zero size, unlike electrons, which are considered elementary particles and are point-like with zero size. The discussion emphasizes the distinction between classical and quantum interpretations of particle size, specifically addressing whether neutrons should be treated as point particles. The reference to the Physics Forums thread provides additional context on the size of neutrons.

PREREQUISITES
  • Understanding of particle physics terminology
  • Familiarity with the concepts of composite and elementary particles
  • Knowledge of classical versus quantum mechanics
  • Basic grasp of the Standard Model of particle physics
NEXT STEPS
  • Research the properties of composite particles in the Standard Model
  • Explore the implications of quantum mechanics on particle size
  • Study the differences between point particles and extended particles
  • Investigate experimental methods for measuring particle sizes
USEFUL FOR

Students and professionals in physics, particularly those focusing on particle physics, quantum mechanics, and the Standard Model, will benefit from this discussion.

For example should a neutron be considered as a point, or does it have volume?

If treated as classical particles, then I believe they are considered as point particles.

Neutrons are composite particles, not elementary particles, and thus would have a non-zero size. An electron, being an elementary particle, is point-like. It has zero size.
