An electron is the carrier of the negative electrostatic force, and it has a charge of -1. Also, the electron, along with the proton and neutron, are the "basic building blocks" of atoms, and they make up the matter all around us. The positron, on the other hand, is an anti-electron - it's antimatter! And it is the antiparticle of the electron. It has a charge of +1, which is just the opposite of the electron's. The fact that the electron and positron are matter and anti-matter, and that they have a charge of -1 and +1 respectively are the major differences. A positron is an electron's anti-particle, and when the electron and positron come in contact with each other to combine, they annihilate each other in a process called electron-positron annihilation. There is a link below to that related question and to a couple of others.

Why do antimatter and matter react when they touch what's the chemistry of it?
Matter-Antimatter reactions are not chemical reactions. They are very complex sub-atomic reactions, and the nature of the annihilation depends on the matter and anti-matter in the reaction.One of the simplest matter-antimatter annihilations is between an electron and a positron (an anti-electron). The electron has a negative charge and the positron has a positivecharge. When they come in to contact (under the right conditions) they must annihilate, since one cancels out the other.However matter cannot simply dissappear, so it must be converted to energy via E = mc^2 where E is the energy released, m is the combined mass of the electron and positron, and c is the speed of light.In the case of the electron-positron annihilation this results in two gamma rays of a certain energy.As the size and complexity of the matter-antimatter reactions increases so does the complexity of the reactions.
Why the suffix of atomic particles is on as proton neutron positron electron?
In 1894 the physicist Stoney proposed the name electron(on being a Greek suffix); the names of the other elementary particles were formed by imitation.
Why is it that sometimes when a very high energy electron hits a target material a positron and two or more electrons come out of the event?
An electron at high energy entering into a scattering event will bring all that energy with it. All that energy will have to be "dealt with" in the outcome. One way that a big chunk of it can be "handled" is almost magical. A large portion of the energy can be transformed into an electron-positron pair. This event is called pair production. We usually see it when a high energy gamma ray causes it, but it can be one of the outcomes in an energetic electron collision. The production of this pair of particles is the direct result of the conversion of energy into matter, and it will carry off a lot of the energy in the event. The minimum energy need to create the pair is 1.022 MeV. The original electron is still "in one piece" after the event, so it may look like the single electron crashed into a target and two electrons and a positron came away. It was actually the original electron and that electron-positron pair. If the original electron ionized another electron (or more) in the target material (which is possible), they will come away as well. Certainly there are a number of possible outcomes in an energetic electron scattering event, but pair production is one of the possible outcomes, depending on the energies involved and the target material.
Can a virtual photon create muon antimuon and tau antitau pair instead of electron positron pair?
Yes, although the heavier pairs are less likely to be found, it is not impossible.
What is the difference between a positron and electron and a nutrino?
A positron is like an electron in every way but charge, electrons having -1, positrons having +1. In other words, they're a positron is an electron's antiparticle. Neutrinos are chargeless, pointlike, nearly massless particles associated with electron and positron decays that exist in order to preserve the conservation of energy, momentum and angular momentum in these decay processes.
What is the antiparticle of a positron?
Since the positron is the antiparticle of the electron, it follows that the electron is the antiparticle of the positron.
Does positron have a negative charge?
A POSITron has a POSITive charge, hence the name. A positron is an anti-electron; since the electron has a negative charge, the positron has a positive charge.A POSITron has a POSITive charge, hence the name.

A positron is an anti-electron; since the electron has a negative charge, the positron has a positive charge.
What the difference between positive and negative electrons?
an electron always has a negative chargea positron is identical in all respects to an electron (sometimes it is called a "positive electron"), except it always has a positive charge and is antimatter (not matter)If an electron and a positron meet they will both cease to exist (annihilation) and gamma ray photons will be created.
Can annihilation of matter occur between a positron and neutron?
No, a positron cannot react with a neutron in any kind of annihilation reaction. An electron and a positron can, and the same with a neutron and an anti-neutron, but it does not occur between a positron and a neutron.
What is the antimatter version of an electron?
positron
How is a positron different from an electron?
A positron is an electron's antiparticle. It has the same mass as an electron, but an opposite electrical charge.
What is the anti-matter equivalent of an electron?
No. The antiparticle for the proton is called antiproton. The antiparticle for the electron is called antielectron, also known as positron.
Why does antimatter anihilate matter and Would a positron anihilate a muon or a quark?
A positron is the antiparticle of an electron; in other words, it is an alternate name for the "anti-electron". Therefore, a positron would anihilate with an electron. I am not sure about the "why".
How do positron emission and electron capture change an atom?
After positron emission or electron capture the atomic number is decreased with one.
What are the properties of a positron?
Very similar to an electron, with the main difference that it has a positive charge instead of a negative charge.
What is the anti-particle of an electron?
That is called an anti-electron, also known as a positron.That is called an anti-electron, also known as a positron.That is called an anti-electron, also known as a positron.That is called an anti-electron, also known as a positron.
