In an atom, there are 3 types of particles: protons, neutrons and electrons.
Theoretically, protons and neutrons weight 1 Atomic Mass Unit. An electron weights 1/1836 of an Atomic Mass Unit. Therefore, in an atom, electrons weigh the least.
What else can I help you with?
What one of a nucleus proton and neutron have the least amount of mass?
A proton has slightly less mass than a neutron.
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.
Which has least mass neutron protron electron or nucleus?
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 mass of a proton and does a proton have mass?
Yes, a proton has mass. The mass of a proton is approximately 1.67 x 10-27 kilograms.
What particles the one with the least mass is the electron proton neutron or neutrino?
Neutrinos, but their mass is very, very small.
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.
Does a proton have mass?
Yes, a proton has mass.
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 subatomic particle has the less mass?
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
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.
Of the three main subatomic particles the has the least mass?
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 is equal to mass of a proton?
The mass of a proton is equal to a neutron.
