A Neutron weighs more than a proton. Than an electron.
A Neutron weighs the most, and an electron weighs the least. A proton is in the middle. Although there are these three sub atomic particles, an atom is made up of 99 percent empty space! But from greatest to least in mass, it goes neutron, proton, then electron!

What part of an atom has the least mass?
the electron is the least massive atomic particleelectron
What is an uneven distribution of charged in an atom?
Proton: positive charged Electron: negative charged Neutron: neutral
Protons are so much more massive than electrons that you can neglect the mass of electrons when determining the mass of an atom?
Atomic mass is based on the proton and neutron. For the most part the mass of an electron is infinitesimally small.
What are the weights of the subatomic particles?
I think you probably mean the mass of the classical subatomic particles, Proton, Neutron and Electron. From memory, the mass of the proton and neutron are almost the same and approximately 1.6 x 10-24 grams while the mass of an electron is about 0.9 x 10-28 grams. In the Standard Model of subatomic particles, there are very many more particles than these three and their masses are best looked up in tables. Some of the masses of subatomic particles have not yet been determined (neutrinos) and one of the theoretical particles has not yet been shown to exist at this time (Higgs boson).
List three main particles of an atom and explain how they differ from one another?
Protons and neutrons are found in the atom's nucleus and represent practically all of an atom's mass. Protons are positively charged, while neutrons are neutral. Electrons orbit the nucleus in regions called energy levels (or shells) and carry a negative charge.
Does an electron have more maas than a proton or neutron?
an electron is much lighter than a proton or neutron.
Why does the neutron have the most mass in an atom?
Yes, a neutron has more mass than a proton or electron.
How does the mass of an electron compare to that of a neutron?
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
Is the electron the largest of the three main atomic particles?
The electron is the smallest of the three main atomic particles by a long way. The proton and neutron are of a similar size, with the neutron having (very) slightly more mass. The mass of an electron is around 1/1840 of a proton or electron.
What particle has the same mass as a neutron?
A positron, a neutron, a single proton, and a single electron are all considered to be equal in mass, however, a positron is generally referred to as an "anti-electron", as it travels at the velocity of light (like an electron), an has a positive charge (+1e, as opposed to an electron, which carries a negative charge, i.e: -1e).
In the electron charge to mass experiment if the electron is replaced by a proton or neutron would the charge to mass ratio value still be the same why or why not?
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
Has no charge and weighs slightly more than a proton?
I'm pretty sure it's a neutron.
Is the electron or the neutron or the proton lighter?
The electron, the neutron and the proton are the building blocks of the atom. And of the three, the electron is far and away the lightest. The neutron is slightly heavier than the proton, and either particle is over 1800 times more massive than our little electron.
Does electron weigh more or less then proton and neutron?
Protons are made up of Subatomic Particles, in this case a Proton Atom is made up of two Up quarks, and one Down quark. The mass of an Up Quark is 2.4 MeV/c2 and the mass of a Down quark is 4.8 MeV/c2. Electrons are still in the Subatomic Particle Table, an Electron is a type of Lepton. An Electron's mass 0.511 MeV/c2 which is a lot less than a Proton, even less than a Up quark itself (the lightest quark). In most cases when talking about Atoms and their mass Electrons don't normally have an effect on their mass, only the Neutrons and Protons in the Atom. This should answer the Question.
Do protons and neutrons have nearly the same mass?
No, the proton and neutron don't have the same mass. A neutron is about 1.00138 times as heavy as a proton. The neutron is just a bit bigger, as you can see, and when a free neutron decays, it releases a proton and an electron. It might be said that a proton plus an electron equals a neutron, but you might not be able to get a physicist to say that. Links can be found below for more information.
In beta-minus decay is it the appearance of an electron that makes the neutron and proton balance each other or a dynamic force of neutron and proton that produces the electron?
It is a confusing subject and it gets worse the more you get into it! Basically, in beta-minus decay, a neutron changes into a proton within the nucleus, and an electron and a neutrino are emitted. This is put down to the weak nuclear force. The theory goes that a down quark in the neutron changes to an up quark by emitting a W boson which then becomes an electron and a neutrino, whilst the neutron becomes a proton. That said, I am not sure what you mean by 'neutron and proton balancing each other', as the reaction is more like your second proposition. The isotope in question then becomes the element with an atomic number one higher than the original, because now it has an extra proton, though its atomic weight is almost the same.
What is the weight of a proton?
A proton weighs approx. 1 Atomic Mass Unit (A.M.U). this weight is the same as a Neutron, but an electron weighs about 1/2000 of an A.M.U. Hope this helps!
