SUMMARY
The radius of fundamental particles such as electrons, protons, and neutrons is a key topic in atomic physics. Electrons and quarks are considered pointlike particles with no defined radius. Protons and neutrons, referred to as nucleons, typically have a radius of approximately 1 femtometer (fm), or 10-15 meters. The definition of these radii can vary based on the context of measurement and theoretical frameworks.
