Atoms: Protons, Neutrons, & Other Particles?

Click For Summary

Discussion Overview

The discussion revolves around the composition of atoms, specifically focusing on the roles of protons, neutrons, and electrons, while also questioning the existence and relevance of other particles such as leptons and hadrons in the context of atomic structure. The scope includes conceptual understanding and exploration of exotic atoms.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • One participant questions the traditional view that atoms consist solely of protons, neutrons, and electrons, seeking clarification on the role of other particles like leptons and hadrons.
  • Another participant suggests looking into exotic atoms as a potential source of information regarding additional particles in atomic structure.
  • A participant inquires about the production of exotic atoms, indicating a curiosity about how these particles are formed.
  • It is noted that high-energy collisions at facilities like CERN and Fermilab can create new particles, implying a connection between energy and particle production.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the role of exotic particles in atomic structure, and multiple viewpoints regarding the composition of atoms and the existence of exotic particles remain present.

Contextual Notes

The discussion does not resolve the definitions or implications of exotic atoms, nor does it clarify the conditions under which additional particles are considered part of atomic structure.

Just one quick question I couldn't find an answer on the internet to, after a long search.
We are taught that atoms are made from protons, neutrons and electrons only. There are many other leptons and hadrons existing, but where are they in this story?
 
Physics news on Phys.org
Okay, so in a usual atom, only protons, electrons and neutrons exist. But how are those exotics produced?
 
You smack "normal" particles together with high energies at places like CERN and Fermilab. Some of the energy creates the masses of the "new" particles.
 
Okay, thanks.
