What would have been the charge of the new nucleus formed if the beta particle had been a positron?
When a positron is emitted a proton is converted into a neutron. Therefore the new nucleus will have a positive charge that is one less than its previous charge.
How is isotope produced?
An isotope can be produced if a nucleus gains a neutron or if one of the protons in its nucleus decays into a neutron and positron.
The nuclear fusion of a helium-3 nucleus and nuclide X releases an alpha particle and a positron Identify nuclide X?
It is Deuterium an isotope of hydrogen.
What is the process when a parent nucleus reproduces 2 daughter nuclei that are identical to the parent nucleus?
mitosis.
How beta radiations from nucleus when nucleus contain no elements?
Beta is produced by the weak nuclear force.n --> p + e- + v, decay to electron & antineutrinop --> n + e+ + v, decay to positron & neutrinoThe leptons do not preexist in the nucleus, their wavelength would be too long for that.I think you are confused when you say "contain no elements". No nucleus contains elements, the nucleus is part of an atom and atoms are part of elements & compounds.Perhaps you meant to say "contain no electrons". If so you are right, see above. The leptons (electron, positron, neutrinos) are created by a decay process mediated by the weak nuclear force.
What is the daughter nucleus produced when 196Pb undergoes electron capture?
The beta plus decay of mercury (a positron emission event) will deliver the daughter nucleus gold.
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.
How isotopes produced?
An isotope can be produced if a nucleus gains a neutron or if one of the protons in its nucleus decays into a neutron and positron.

Why do positron emission and electron capture have the same effect on a nucleus?
The reason positron emission and electron capture have the same effect on the nucleus of an atom is because the resulting atom undergoes nuclear transformation, and the new element will have one less proton and one more neutron than the precursor element. Both of these nuclear changes are interesting, so let's look a bit more closely. In positron emission (also called beta plus decay), a proton in the nucleus of an atom "changes" into a neutron and a positron is ejected. This results in one less proton in that nucleus (naturally), and the creation of a new element. And because the proton had become a neutron, the nucleus has the same number of nucleons and a similar atomic weight. In electron capture, a nucleus with "too many" protons will actually "pull in" an electron and take it into its nucleus. This electron will "combine" with a proton, and a neutron will result. This will reduce the number of protons in the nucleus, and the creation of a new element -- just like in positron emission. Links to related questions can be found below.
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.
Is there a positron in the nucleus of an atom?
There are no positrons in the nucleus of any atom. Positrons are anti-electrons; they are antimatter. They could be said to be the antimatter equivalent of the electron, and, as such, they would be present around the nucleus of an antimatter atom as the electrons are present around the nucleus of a "regular" atom. Positrons can be produced in atomic nuclei by some kinds of radioactive decay, and they can be observed to be leaving a nuclear reaction called beta plus decay. But the positron leaves the nucleus of an atom as soon as it is created. It does not (cannot) exist in the nucleus of an atom.
The emission of a positron also results in the creation of a?
When an atomic nucleus releases a positron, it has undergone beta plus decay. This nuclear transformation event also will release a neutrino. Use the link below for more information.
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.
Which of the following particles has the same mass as an electron but a positive charge and is sometimes emitted from the nucleus during radioactive decay?
A positron.
When radioactive phosphorus decay it emits a positron will the resulting nucleus be another isotope of phosphorus?
No, whenever an atom emits a positron its atomic number is decreases by one unit (because a proton is converted into a neutron and a positron) but atomic mass remains the same so phosphorus is converted into silicon atom with same atomic mass.
