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.
What is electron capture?
Simply put, electron capture is a nuclear change that an atom might undergo when there are "too many" protons in its nucleus. This atom is unstable, and an electron from an inner orbit will actually be "pulled into" the nucleus. Once there, the electron will "combine" with a proton, and the proton will be transformed into a neutron. This will result in the formation of a new element as a result of the nuclear transformation.
Electron capture by DPIP?
Electron capture by a dye like DPIP (2,6-Dichlorophenolindophenol) usually leads to a color change in the dye molecule. In this process, the dye molecule accepts an electron from a reducing agent, causing the dye to change from blue (oxidized form) to colorless (reduced form).
What is an electron transition?
The electric dipole transition refers to the dominant?æeffect of the atom's electron interaction in the electromagnetic field. It is also the transition between the system energy levels with?æthe Hamiltonian.
When a beta particle is emitted does the mass number of the isotope remains unchanged?
With the ejection of a beta particle (electron), there is a minute loss of mass. Electrons have very low mass. The atomic number increases though as a neutron is transformed into a proton. A antineutrino is also ejected. In a similar process, positron emission also called beta decay,- a positron is emitted and a proton is transformed into a neutron, the atomic number decreases. A neutrino is also ejected.
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.

How elements can change in nuclear reations using balance equations?
Alpha decay, Beta decay, Positron emission, and Electron capture can change one element into another as follows. Alpha Decay: 18675Re -> 18273Ta + 42He Beta Decay: 18675Re -> 18674W + 0-1e Positron Emission: 18274W + 01e -> 18275Re Electron Capture: 18274W + 0-1e -> 18273Ta Because of the decay emission or capture, the element's atomic makeup can change - making it into another element. Re-75 can go through Beta Decay, making it W-74 Hope this helps, if anyone else reading this finds an error please correct it, I'm going off of memory from my chemistry class and cannot cite any textual references for the information given.
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.
Which particle is associated with beta decay?
The atomic nucleus can emit beta particles (beta radiation). A neutron emits a beta particle when it decays into a proton, and anti-neutrino, and an electron (which becomes the beta particle).

What is the nuclear equation for positron emission by sulfur 31?
If molybdenum-91 undergoes beta plus decay, or positron emission, the equation will look like this: 4291Mo => 4191Nb + e+ + ve In this reaction, a proton in the nucleus of the Mo-91 atom undergoes a change mediated by the weak interaction or weak force. This involves an up quark changing into a down quark, and the proton becomes a neutron. Nuclear transmutation takes place, and the Mo-91 atom becomes an atom of niobium, Nb-91. The positron, represented by e+, and a neutrino, the ve, will be ejected from the nucleus. Links can be found below if you wish to check facts and do some additional investigating.

What changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2
Is charge of a baryon conserved when it undergoes beta decay?
Total charge is always conserved. If an electron is emitted, the remaining particle's charge will change by +1. If a positron is emitted, the remaining particle's charge will change by -1.
Are beta particles are electrons detached from the nucleus?
During nuclear decay when a beta- particle (a high energy electron coming from the decay event) leaves the nucleus, the action is the result of the transformation of a neutron into a proton and an electron (the beta- particle). Got links if you want them. They are to related articles posted by our friends at Wikipedia, where knowledge is free. Note: there is a bit more to beta decay than was mentioned here, but enough was presented to answer the question. Certainly it is hoped that the links will extend knowledge about as far as the average reader may wish to go.
Is it possible to positively charge an electron?
No, not quite. There is a particle called the anti-electron (or, more commonly, the "positron"), which has a positive charge. But you can't really consider it an "electron". In general, the subatomic particles have certain properties fixed, and you can't change them. This includes their mass (rest mass), their spin, and their charge.
