The particle not found in the nucleus is the electron
electrons are found in the electron clouds while protons and neutrons are found in the nucleus
Electrons
No, it is never to be found in the nucleus, it is in electron orbits or 'shells', each with its own the energy level.
The electrons are found in the electron shells
This electron is a valance electron.
Electron is an elemenatry and fundamental nuclear particle; electron has not any components.
The region around a nucleus where an electron might be found is called an electron cloud or electron orbital. It represents the probability of finding an electron at a specific location based on its energy level. The electron cloud is a three-dimensional representation of where an electron is likely to be located within an atom.
