A positron is an antielectron. It's identical to an electron in every way, except that it's made of antimatter and has a positive charge. Positrons have about 1/1000 the mass of protons, they have no measurable volume (and perhaps no volume at all), they are not found in a typical atom, and they annihilate on contact with electrons.
Protons do have a measurable volume, they are found in the nuclei of all atoms, and I don't know what would happen if one contacted an electron, but I'll bet it wouldn't annihilate.

A positron is the anti-electron. It has the same properties of electron except for its charge which is a +1. A proton is found in the nucleus and the only similarity between a proton and a positron is their charge.

Protons are about 1000 times as massive as positrons. The positron is also called an 'anti-electron' because it has most of the electrons characteristics but carries a positive charge.

proton is a particle charged +e . The number of protons Z is the atomic number. It is a matter particle
A positron is an electron with charge positive.it is an antimatter particle which does not exist normally .( Only artificial whereas the negative electron exists). The mass of positron is 1/1836 that of proton

A hollow isn't the completed opposite of an electron. that is a niche in a crystal structure or valance band. convinced, it may flow, yet no longer on the same mobility as an electron. It can also't exist out fringe of the shape that is in. A positron is a effortless particle equivalent to an electron with a cost of +a million instead of –a million. If it skill universal count that is destroyed, develop into potential. A Proton is a heavy particle that exists contained in the nucleus of atoms, and extremely infrequently outside of it. Re charm, holes are not any further debris and haven't any "charm" Re the others, it relies upon on the gap. yet considering that all of them have the same quantity of value, in effortless words on the gap. Coulomb's regulation, stress of charm/repulsion F = kQ?Q?/r² Q? and Q? are the prices in coulombs r is separation in meters ok = 8.99e9 Nm²/C² .

Protons a positively charged particles that form nucleous of stable atoms.
Positrons may occur in the nature and are also positive, but are not stable and annihilate with electron forming photons. You may not get a "beam of positrons" in a lab... Like electorns, they are much lighter (1000 times) than protons.

A positron is an electron that has a positive charge. This is part of antimatter.
A proton is in the nucleus, larger and assumed positive unless stated otherwise.

A positron is like an electron (but positive), not like a proton.
