Protons are converted into neutrons during positron emission to satisfy certain conservation laws, like charge and baryon number.
The following reaction takes place during positron emission:
p+ --> n + e+ + ve, where p+ is a proton, n is a neutron, e+ is a positron (antielectron), and ve is an electron neutrino.
Charge is +1 on both sides of the reaction, and so is conserved.
Baryonic number is 1 on both sides of the reaction (both the p+ and the n have baryonic numbers of 1), and so is conserved.
Also, lepton number is 0 on both sides of the reaction (e+ has a lepton number of -1 while ve has one of +1, thus adding up to zero), and so is conserved.

Does beta decay occur during the rearrangement of protons and neutrons in the nucleus?
Yes, beta decay is one of the processes that can occur during the rearrangement of protons and neutrons in the nucleus. Beta decay involves the transformation of a neutron into a proton or a proton into a neutron, along with the emission of a beta particle (electron or positron) and a neutrino.
What conditions in the nucleus are likely to result in an atom undergoing radioactive decay?
A nucleus can be inherently unstable. It can absorb an energetic photon (photoactivation) and become unstable. It can capture positrons, electrons, neutrons, and protons and become unstable. Decay processes include: # Alpha emission, a high energy 4He nucleus # Beta emission, a high energy electron # Beta+ emission / Beta capture, either a positron is emitted or an electron is captured into the nucleus (Burp!) # Gamma emission, one or more high energy photons are emitted # Neutron emission, neutrons of varying energies may be ejected in the process of a heavy nucleus decay (even tritium).
Can atoms be broken down into smaller particles if Yes then what are the names of the particle?
Atoms consist of protons, neutrons, and electrons. Protons and neutrons, in turn, are made up of quarks.Atoms consist of protons, neutrons, and electrons.

What is the place where protons and neutrons?
the nucleus is where protons and neutrons are if that's what you were asking
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 does an isotope release as a beta particle?
Usually when isotopes undergo beta decay they emit an electron, but some isotopes emit a positron instead. This depends on the relative number of neutrons to protons in the isotope which type of beta particle is emitted. An excess of neutrons leads to the emission of an electron, while an excess of protons leads to the emission of a positron.
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.
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.
How do positron emission and electron capture change an atom?
Positron emission results in the atom losing a proton, transforming the atom into a different element with a lower atomic number. Electron capture involves the atom gaining a proton, resulting in the transformation of the atom into a different element with a higher atomic number. Both processes lead to the formation of a more stable nucleus by adjusting the ratio of protons and neutrons.
What is radioactivity types of radioactivity?
Radioactive decay has nothing to do with chemistry and therefore may not be a chemical reaction. But since matter changes its properties (they are even irreversibly) it is considered to be reaction of one (elemental) reactant. Most decay reactions are kinetically of zero order.Different types of radioactive decay include decay by alpha emission (emits an alpha particle, 2 protons and 2 neutrons), Beta - emission, and Beta + emission (positron emission or electron capture).Some radioactive materials also output gamma rays, protons, neutrons, and can decay by fission.
Do neutrons orbit outside the atom?
No, neutrons do not revolve around the nucleus. Protons and neutrons reside in the nucleus of an atoms. Electrons revolve around the nucleus. Beta emission the release of electron form the nucleus. Alpha emission is the emission of helium atom.
What is the nuclear equation radionclide X decays by alpha emission into radium-224?
Alpha emission means that an alpha particle (2 protons + 2 neutrons) are emitted, so the original nucleus has 2 protons and 2 neutrons more.
The process of positron emission results in a change to the atomic nucleus. Is that change a decrease of 1 or a decrease of 2 or an increase of 1 or is there no change?
In positron emission, atomic number decreases by one. That's because a proton in the nucleus of the element that is about to undergo positron emission changes into a neutron. This is beta plus decay, by the way. You'll recall that the atomic number of an element, which is that element's chemical identity, is determined solely by the number of protons in the nucleus. If we "lose" a proton because it changes into a neutron, atomic number will now decrease by one. Check out the links below to related posts.

If the nucleus of an atom has a proton number of 6 and a mass number of 14 and it undergoes beta transmutation what will be the number of neutrons in the parent nucleus?
The results of beta transmutation will depend on which beta decay even occurs. If it's beta minus, a neutron will be converted into a proton and an electron will be ejected from the nucleus. The original atom with its 6 protons and 8 neutrons (6 + 8 = 14, the mass number as specified) will be an atom with 7 protons and 7 neutrons. In a beta plus decay event, a proton will be converted into a neutron and a positron will be ejected from the nucleus. The original atom with its 6 protons and 7 neutrons will be an atom with 5 protons and 8 neutrons. In addition to the ejected electron or positron, there will also be an ejected antineutrino or neutrino (respectively). Use the links below for more information on beta decay.
