A positron is the antimatter counterpart of an electron, with a positive charge, while a proton is a subatomic particle found in the nucleus of an atom, with a positive charge.

Where does the positron produced during positron emission come from?

In positron emission, the positron is produced from the nucleus of an atom when a proton is converted into a neutron and a positively charged positron. This process helps to make the nucleus more stable by decreasing the number of protons.


What radionuclide decays to Br-73 by positron emission?

Work backwards. Positron emission means (essentially) a proton decayed into a neutron/positron pair. The mass number remains the same, but the atomic number goes down one to Bromine. Krypton has an isotope that fits this bill.


How does positron emission cause nuclear transmutation?

It is in beta plus decay that we see the positron emitted from the nucleus. (An electron is emitted in beta minus decay.) Within the nucleus of an unstable atom, a proton transforms into a neutron, and a positron is ejected from the nucleus (along with a neutrino). As the nucleus now has one more proton than it did before, its atomic number just went up by one; it is another element.


Mercury-201 undergoes positron emission?

In positron emission, a proton in the nucleus is converted into a neutron, leading to the emission of a positron and a neutrino. Therefore, in the case of Mercury-201 undergoing positron emission, the nucleus transforms into a new element with one less proton and one more neutron in its nucleus.


What is positron capture?

The decay of an unstable atom by absorbing a wandering positron into the nucleus, converting a neutron into a proton. One example is how a radioactive form of iodine, 131I, can use positron capture to become xenon, 131Xe. This is a stable, so the conversion is a big help.

What is the difference between a proton and antiproton?

AnswerThe difference between a proton and a positron is threefold. First, the proton is much more massive (a bit over 1800 times) than a positron. Second, the positron is an elementary particle (though it is antimatter), while the proton is made up of three elementary particles called quarks (two up quarks and one downquark). Third, the positron is antimatter while the proton is "regular" matter. Protons are stable particles (they are hydrogen-1 nuclei), and positrons are produced in positron emission (a type of radioactive decay) or in pair production (where a high energy gamma ray "splits" into an electron and a positron when passing near an atomic nucleus). After a positron appears, it will eventually (and in a relatively short period) combine with an electron in an even called mutual annihilation, and both particles will be converted into energy.Both the proton and positron have a charge of +1, and you can review more information by using the links below to the related questions about the proton and the positron.AnswerA proton is a particle found in the nucleus. It has a positive charge of +1. (Depending on how versed you are, this is equivalent to + 1.60 x 10-19 C of charge). The proton actually is comprised of three smaller subatomic particles called quarks, two up quarks (+2/3) and one down quark (- 1/3). The electron on the other hand is a fundamental particle in that it is not made up of anything smaller (that we know of yet). It has a -1 charge (again - 1.60 x 10-19 C). A positron, however, is antimatter. It is the antimatter of an electron. For intents and purposes it is an electron with a positive charge. If an electron and a positron should interact, they would annihilate one another.

What is the positron emission from silver 31?

Silver-31 undergoes positron emission to form palladium-31 by emitting a positron (e+) and turning one of its protons into a neutron. This reaction helps stabilize the nucleus by converting a proton into a neutron.


Positrons have the same charge as what other particles?

A positron, which has a positive charge, has the same charge as a proton. The positron is antimatter, and is the antiparticle of the electron, hence its other name, the anti-electron. The electron has a charge of negative one, so its anti-particle, the positron, has a charge of plus one, the same as the proton. Links are provided below to related questions.


What is the difference between a positron and an electron?

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.
