Well, that's kinda a trick question because an electron is pure energy. An electron particle is also the smallest of the 4, so its the electron (eventhough an electron is a weichtless particle such as a graviton or magneton!
Hope I helped!!

What is the smallest and least energetic path of the electron around a nucleus?
ground state
Why is it harder to remove an inner shell electron than a valence electron from an atom?
Electrons are attracted to the positive charge on the nucleus. The further an electron is found from the nucleus of an atom, the lower the force of attraction between it and the nucleus. Therefore an electron far away from the nucleus (like a valence electron) will have less of an attraction to the nucleus than one close to it. A lower attraction to the nucleus translates into the fact that less energy would then be required to remove the electron from the vicinity of that nucleus.
What region of an atom has the least mass?
The space surrounding the nucleus.
Why cesium is regarded as least electronegative element?
Cesium is a group one metal which has a large atomic radius. This means that the outer shell of electrons is a great distance away from the pull of the nucleus which causes a decrease in the affect of the nuclear charge. There are many electron shells in between which causes shielding. This would reduce the atom's ability to pull electrons in a bond making it less electronegative. Group one elements would rather lose their outer shell electron to become stable than gain another electron.
Where are the electrons that possess the least amount of energy located in a calcium atom in the ground state?
An electron in the third shell has more energy than an electron in the second shell.
Which has least mass protron or electron?
An electron.
Which particle is the least massive a proton nuetron electron or nucleas?
electron is least, followed by proton and then neutron. Nucleus will have the highest mass as nucleus contains both protons and neutrons.
Who has the smallest mass electrons protons or neutrons?
Of the neutron, proton, and electron, the electron has the smallest mass.
Which has the least amount of mass a molecule an atom an electron a neutron a proton?
The mass of an electron is the least among the options given here.
The nucleus contains both protons and electrons?
No! The nucleus of an atom consists of at least one proton and, in all but one instance, at least one neutron. An atomic nucleus does not include electrons.
What one of a nucleus proton and neutron have the least amount of mass?
A proton has slightly less mass than a neutron.
What are the parts of an atom from largest to smallest?
An atom consists of three basic components: electrons, protons and neutrons. The three particles are listed in order of least massive to most massive. A neutron is slightly more massive than a proton, and these two particles make up the nucleus of an atom. Electrons are the smallest particles found in an atom, and an electron is less than 1/1800th the mass of a proton. They are so small that their mass is not even taken into consideration when calculating the mass number (protons plus neutrons) of an atom, even in larger atoms with large numbers of electrons.
What has the least mass - electron neutron proton nucleus?
LEAST mass? That would be photos or neutrinos, which have no mass at all. Where Least is greater than zero? Electrons, probably; an electron is 1/1836th of a proton, I seem to recall. Neutrinos actually have a small nonzero mass, so small it has yet to be determined. No neutrino has a mass of more than a few eV, the electron has a mass of about 0.5MeV.
Particles found in the nucleus of an atom?
The nucleus of an atom always contains at least 1 proton. It almost always contains at least 1 neutron as well.
Which subatomic particle has the smallest mass alpha particle neutron electron proton?
among these Electron has the least mass....
What is the region around a nucleus where an electron might be found?
The place around the nucleus where an electron can be found is called the ORBITAL . Accordingly the place where the chances of finding an electron are the least is known as 'NODE' .
Why does every element except hydrogen need at least one neutron in its neucleus?
Every element except hydrogen needs at least one neutron in its nucleus because it needs attractive force from the strong nuclear interaction to counter the electrostatic repulsion between the protons.
