To preserve the conservation of; energy, momentum, and angular momentum in beta plus decay. Without the neutrino there is a measurable difference between the energy, momentum, and angular momentum of the initial and final particle. The neutrino rectifies this difference and it's existence was actually postulated before it was ever discovered!

What is the reaction for C 14 for Positron Emittion?
Carbon-14 (C-14) undergoes positron emission as part of its radioactive decay process. During this decay, a neutron in the carbon nucleus is converted into a proton, resulting in the emission of a positron (the antimatter counterpart of an electron) and a neutrino. The reaction can be represented as: [ ^{14}{6}\text{C} \rightarrow ^{14}{7}\text{N} + e^+ + \nu_e ] This transforms the carbon-14 atom into nitrogen-14 (N-14).
Why are protons converted into neutrons during positron emission?
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 is a proton in the nucleus converted into what during electron capture?
During electron capture, an electron and proton combine and are converted to a neutron.
Which particle is emitted during the nuclear decay of Ne-19?
During the nuclear decay of Ne-19, a positron is emitted.
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.
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.
Why are protons converted into neutrons during positron emission?
Protons are converted into neutrons during positron emission to satisfy certain conservation laws, like charge and baryon number.

What is emitted during beta decay?
During beta decay, a beta particle (either an electron or a positron) is emitted from the nucleus of an atom. This emission occurs when a neutron in the nucleus is transformed into a proton, with the accompanying release of a beta particle and an antineutrino (in the case of beta-minus decay) or a neutrino (in the case of beta-plus decay).
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 is the kind of decay that occurs when a nucleus releases a positron?
There is technically no such thing as positron decay. It's a misnomer. The nuclear decay process wherein a positron is emitted from a decaying nucleus is called positron emission or beta plus decay. A link is provided below that question and its answer.
What method of studying the brain involves the insertion of radioactive glucose (sugar) into a vein?
The method is called positron emission tomography (PET). Radioactive glucose is injected into the bloodstream, and imaging technology detects the radioactive particles to show brain activity and metabolism. This helps researchers understand which brain areas are active during specific tasks or at rest.
What is a proton in the nucleus converted into what during electron capture?
During electron capture, an electron and proton combine and are converted to a neutron.
Will there be an increase in mass during beta decay in nucleus?
If you are asking whether the nucleus' mass would increase, the answer is no. Beta decay involves emission of an electron from the nucleus. This happens when a neutron converts to a proton, an electron, and an anti-neutrino. A neutron is heavier than a proton, and the anti-neutrino carries away some energy with it, so the mass of the nucleus decreases.
What can positrons do?
Positrons are anti-electrons; they're antimatter. There are a couple of sources of positrons, and in our universe, the positron is looking for an electron to combine with so it can return from whence it came. This process, called mutual annihilation, sees the positron combine with the electron to produce two fairly high energy gamma rays (leaving the scene in opposite directions). In another universe, an antimatter one, the positron orbits around antimatter atomic nuclei. It also forms positricity in that universe. The positron is also used in medical imaging in positron emission tomography (PET) scans. The positron doesn't have a lot of penetrating power, and it won't travel far after it is released. But it is worth noting that those gamma rays that are released when a positron and an electron mutually annihilate each other are pretty high energy ones. They have a lot of penetrating power, and they can do considerable biological damage if a living thing is exposed to a positron source for too long. The PET scan only ends up "minimally exposing" an individual during the procedure, in case you're wondering. Links can be found below for more information.
What is generated in the suns core?
Helium is generated in the core of our sun by nuclear synthesis .During the nuclear fusion inside the sun , hydrogen is fused into helium .the main products generated in this reaction are - Gamma ray photon, positron, neutrino, isotopes of hydrogen and helium and large amount of energy .
What radiation is emitted during beta decay?
During beta decay, a beta particle (an electron or positron) is emitted, along with an antineutrino or neutrino, depending on whether it's beta-minus or beta-plus decay, respectively. Beta decay involves the transmutation of a neutron into a proton within the nucleus, releasing the beta particle in the process.
