Why does the neutron have the most mass in an atom?
Yes, a neutron has more mass than a proton or electron.
What particle most resembles a proton?
The particle that most resembles a proton could either be a neutron or an electron, and we'll have to explain that. The proton has about the same mass as the neutron, while the electron has only about 1/1836th the mass of a proton. The masses of the proton and neutron are similar. And both particles are found in the nucleus of atoms. The proton has the same electrical field strength as an electron (only of opposite polarity), while the neutron has no charge. The proton and electron have the same coulomb charge on them, except the sign of the charge. Both particles are carriers of fundamental electrical charges. In these two ways, the proton could be said to be like either the neutron or electron. And how the observer "looks" at them will determine which "likeness" he sees.
Why is most mass of the atom is in the nucleus?
Because proton and neutron are in about one thousand times heavier than 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.
Which weighs more proton neutron electron?
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!
Is Most of the mass of an atom is in the nucleus?
Because proton and neutron are in about one thousand times heavier than electron.
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.
True or false the mass of a proton is about one atomic mass unit?
False - an electron is about 1/1836 the mass of a proton.
What is smallest atom neutron electron or ion?
The electron is the smallest of these entities, being a subatomic particle with a mass much smaller than that of a neutron or an ion. Neutrons and ions are composed of multiple subatomic particles and have greater mass compared to electrons.
Which particle is not found in the nucleus?
Atoms are the building blocks of matter. Atoms are made up of electron, neutron and proton particles. Electrons are negatively charged, neutrons are neutral and protons have a positive charge.
What is the mass on proton neutron electronic?
The mass of a proton or neutron is approximately 1 amu. The mass of an electron is about 1/1836th of an amu. In chemistry, the mass of electrons is usually treated as insignificant (certain very precise measurements can actually detect them, but treating the atom as if all its mass was in the nucleus is "good enough" for most purposes).
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.
