The smallest particles that have been discovered and that don't only exist in theory are the quarks. They are what make up protons, neutrons, all kinds of baryons, and a few other categories of particles. But there is a theory of smaller particles that make up quarks, electrons, and other particles that were previously believed to be fundamental (But, again, these particles only exist in theory). These particles are to be called "rishons" if discovered.

Which particle has the least amount of mass?
The 'rest mass' of the photon is zero ... but the photon is never at rest, and it has plenty of mass at the speed of light, at which it is always traveling. so that let's the photon out. Amongst particles that actually have rest mass, but not much of it, the neutrino probably has the least.
What particle determines the mass along with the protons of an atom?
The particle is called the "Quark"
What particle in the atom is the least massive?
least - electron most - the top quark
A postively charged particle in an atom?
The positively charged particle in an atom is the proton. The negatively charged particle is the electron. The electrically neutral particle is the neutron.
Which subatomic particle has the smallest mass alpha particle neutron electron proton?
among these Electron has the least mass....
Which in an atom has the least mass in an atom?
Which particle? The electron.
What particle found in an atom has the least mass?
the electron
What stable particle found in an atom has the least mass?
the electron
Subatomic particle that has the least mass?
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
When a beta particle is released from an atom does the atom gain or lose mass?
When a beta particle is released, the atom's mass remains approximately the same because it loses an electron, which has such a small mass in comparison to the whole atom that it is negligible.

Which particle of an atom has the less mass?
The Electron.
What sub atomic particle does not particitpate in the calculation of mass of atom?
Mass of electron is not included for the calculation of mass of an atom.
Which subatomic particle is least massive?
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.
What particle determines the mass along with the protons of an atom?
The particle is called the "Quark"
Which particle has the least mass within 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.
What particle of an atom has the most mass?
It would be neutrons.
