Of the particles you mentioned, the electron has the smallest mass.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
If a proton would be 1, an electron would be 0.000544. An electron is 1,836 times lighter than a proton. A neutron would be 1.001 as a proton is 99.86% the mass of a neutron
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
The electron is the smallest having about 1/1836th the mass of a proton or neutron, which means that basically an electron has no mass. The neutron and proton weigh the same both having a mass of 1.
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
the neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
The mass of an electron is very, very small compared to the mass of a proton and a neutron. The mass of the proton and the neutron are almost exactly the same. Thus, the mass of an entire atom is essential just the mass of the proton plus the mass of the neutron.
atomic units. A proton has a mass of 1 atomic unit, and so does a neutron. the mass of an electron is very small, and almost negligible
This particle is the 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.
