the electron
Which particle? The electron.
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
A neutral particle in an atom is typically found in the nucleus, such as a neutron. Neutrons have no charge and contribute to the atomic mass of the atom.
An electron has the least mass among the three fundamental particles of an atom, which includes protons and neutrons.
least - electron most - the top quark
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or atomic mass units.
A proton is a positive particle with a mass of approximately 1 Dalton. It is found in the nucleus of an atom and carries a positive electric charge.
The Electron.
Mass of electron is not included for the calculation of mass of an atom.
The three particles that make up an atom are protons, neutrons and electrons. Protons and neutrons both have a mass of 1 unit, whereas the mass of an electron is 1/1837 of that of a proton or a neutron. Therefore, the electron has the least mass as its mass is considered negligible.
