SUMMARY

An electron does not have its own nucleus, as it is classified as a fundamental particle within the standard model of particle physics. There is no internal structure to an electron, and extensive experimental evidence, including high-energy electron collisions, supports this conclusion. Unlike alpha particles, which can reveal the presence of a nucleus through scattering, electrons have shown no such effects. Recent measurements have also confirmed the absence of an electric dipole moment for the electron, reinforcing its status as a fundamental entity.

PREREQUISITES
  • Understanding of the standard model of particle physics
  • Familiarity with fundamental particles and their properties
  • Knowledge of atomic structure and Rutherford's gold foil experiment
  • Basic concepts of electric dipole moments in physics
NEXT STEPS
  • Research the standard model of particle physics in detail
  • Study Rutherford's gold foil experiment and its implications for atomic structure
  • Explore the concept of electric dipole moments and their significance in particle physics
  • Investigate high-energy particle collision experiments and their findings
USEFUL FOR

This discussion is beneficial for physicists, students of particle physics, and anyone interested in the fundamental nature of matter and atomic structure.

Hi does an electron by itself have a nucleus?
 
Physics news on Phys.org
Not that I know of.

In the standard model an electron is a fundamental particle, so it has no internal structure

Rutherford inferred the existence of the atomic nucleus by firing alpha particles at gold atoms. Most of the alpha particles blasted straight through as expected, but a few rebounded at sharp angles indicating that they had struck something at least as substantial as the alpha particle itself and that the atom was not a uniform cloud of stuff. No similar effect has ever been observed with electrons (and innumerable experiments over the years have involved highly energetic electron collisions); there is no reason, either theoretical or experimental, to believe that the electron has any internal structure or can be further decomposed.

Thread 'Colors in a plasma globe'

I have a common plasma globe with blue streamers and orange pads at both ends. The orange light is emitted by neon and the blue light is presumably emitted by argon and xenon. Why are the streamers blue while the pads at both ends are orange? A plasma globe's electric field is strong near the central electrode, decreasing with distance, so I would not expect the orange color at both ends.
