Positron
Proton is a positive particle and electron is a negative particle.
Atoms are composed of protons, electrons and neutrons (save hydrogen-1, which lacks any neutrons). Protons and neutrons are baryons, which are made up of three quarks. Having said that, the quark, which is a fundamental particle, is smaller than an atom by a great deal. Further, the quark is smaller than either a proton or neutron, as both are made of three quarks. The electron is a fundamental particle, and it is smaller still than a quark.When we look at the fundamental particles as they are described in the Standard Model, only the photon and gluon, which are force carriers, are smaller. It should be noted that the way we relate "smaller" in this case is by stating a mass-energy equivalence and describing the mass of the fundamental particles in terms of energy.

Positron
electron
Proton is a positive particle and electron is a negative particle.
The electron.
The neutron has the biggest mass; but the mass of proton is very close.
A very small subatomic particle , there will be infinite amounts of these at the dark era of the universe.
It would look very small because subatomic particles are small.
I would say a neutrino, because its charge is zero. ------------------------------------------------------------------------ Neutrino is not considered as a subatomic particle. Proton (positively charged) and electron (negatively charged) have very small electrical charge.
The neutron has a mass very close to the mass of proton (but not identical).
The lightest known subatomic particle is the neutrino. Neutrinos have very small or even zero mass, making them incredibly light. They are electrically neutral and interact very weakly with other particles, making them difficult to detect.
A electron is a subatomic particle outside the nucleus carrying a negative charge and very little mass. Other mass is negligible mass or a negative charge.
