Want this question answered?
particle whose dimensions is less then that of atom are said to be subatomic particle . they may be charged or uncharged .eg neutron is uncharged subatomic particle where as electron ,proton , positron are charged subatomic particle.
In the atom the electron is the lightest.
A proton (or anti-proton).
No. The mass of a proton (1.672622 x 10-27 kg) is only slightly less than the mass of a neutron (1.674927 x 10-27 kg).
The smallest particle is the muon neutrino. The subatomic particles are not measured in size; they are measured in energy. The muon neutrino has an energy of less than 0.170 MeV/c2.

The neutron and the proton. And probably several other less-known particles.
The positively charged particle in an atom is the proton. The negatively charged particle is the electron. The electrically neutral particle is the neutron.

A proton has slightly less mass than a 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.
the neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
The main differences are proton and neutron are in the nucleus, electrons are outside of the nucleus. The weight of an electron is between a hundred and a thousand times less of that of a proton and neutron and the charge on a proton is positive, neutron is neutral and electron is negative
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).
The neutron will not produce a track in the cloud chamber. The neutron, proton, electron and positron are all types of particulate (particle) radiation, and all can do damage, but the neutron interacts much less with the air in a cloud chamber than the other particles will. This means the other particles will leave a tidy little ionized trail behind them on which condensate can form to "paint" the path of the particle. And the neutron will not.
The proton is slightly less massive than the neutron, and the electron is many, many times less massive than either of them. That makes the electron the smallest of the "standard" particles that make up atoms. There are many smaller particles in what is called the particle zoo, but it is hard to sort them out as they are all uniformly unstable and disappear in very short periods of time. The electron is the least massive of the stable subatomic particles that make up the nucleus.Note: We added the last part because the neutron is not stable outside the nucleus of the atoms that it makes up. But of the "big three" particles that are the building blocks of the atom, the neutron, proton and electron, the electron is smallest. It's less than 1/1800th the mass of a proton.
