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.
The electron has only a small fraction of the mass of the neutron. The neutron is about 1837 times as massive as the electron. The proton is just a tiny bit less massive as the neutron, so the proton and neutron are said to have about the same amount of mass.
The mass of an electron is less than 0.001 times the mass of either a proton or a neutron.
If we give them relative numbers, the proton has a mass of 1.0073, the neutron has 1.0087 and the electron has 5.486 X 10 to negative 4.
Mass of neutron: 1,6749 x 10-27 kg Mass of neutron: 1,6749 x 10-27 kg Mass of electron: 0,00091x10-27 kg
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).
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.
Beta particles are actually electrons (-e) or can be positrons.The mass of one electron or beta particle is 9.1095*10-31 kilograms or 0.000548597 AMU which is about 1/2000 times the mass of a proton or neutron.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
The electron has only a small fraction of the mass of the neutron. The neutron is about 1837 times as massive as the electron. The proton is just a tiny bit less massive as the neutron, so the proton and neutron are said to have about the same amount of mass.

Mass ratio proton (neutron)/electron: 1 836
mass of electron = 1/1836 mass of proton (or neutron)
As mass of elactron is very small as compare to proton and neutron So there will be no effect on mass if electron is removed
No, a neutron is about 1836 times the mass of an electron
Mass ratio proton (neutron)/electron: 1 836
Neutron has mass nearly 1,840 times the mass of the electron.
The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron. In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron. In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron. So take your pick: 1,837 to 516,200.
