the electron is the smallest in terms of mass.
9.11E-31kg/electron
1.67E-27kg/neutron
1.67E-27kg/proton
A electron cloud, a electron, protron,neutron,and the nucleus
Smaller than a neutron
An electron.
Electron!
Electrons don't decay, so you probably mean a neutron emitting an electron and becoming a proton? If so, the new atom would be Oxygen.
No, protons and neutrons are in the nucleus and the electrons orbit around the nucleus. This all happens inside the atom.
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!!
A proton and neutron are both composed of three quarks. An electron is a fundamental particle and is not composed of smaller particles.
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.
No, an electron is MUCH smaller than a neutron. About 1/1836 or something like that. Just Google "mass of an electron".
It really depends what particle you are comparing it to. Compared with the neutron and proton: The electron has a much smaller mass - roughly 2000 times smaller than the neutron or proton. As far as we know, the electron is a truly elementary particle. Protons and neutrons are made up of smaller particles (the quarks). The electron has a negative charge, the proton a positive charge, and the neutron is electrically neutral.
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.
