The W boson is the carrier of the weak force (weak interaction), and the weak force is the "boss" of beta decay. The weak interaction mediates the changes that take place in an atomic nucleus just prior to the emission of a beta particle. Let's look at that. In beta decay, one of two things happens. One is that an up quark in a proton becomes a down quark, and the proton becomes a neutron. The weak interaction mediates this, and a W+ boson appears, then becomes a positron and a neutrino. In the other case, a down quark in a neutron becomes an up quark, and the neutron becomes a proton. The weak interaction mediates this, too, and a W- boson appears, and then becomes an electron and an antineutrino. You can use the links below to learn more.

What is the beta decay of radium?
226 Ra 88 ---> 225 Ac 89 +W boson W boson ---> e- + neutron
What does the weak nuclear force act on?
The weak force is the one that allows a quark to turn into a different flavor of quark, thus allowing a neutron to transform into a proton, or a proton to transform into a neutron. In the case of the neutron, one of its down quarks change to an up quark, emitting a W- boson in the process. The boson is itself unstable and rapidly decays into an electron and an electron antineutrino. In the case of the proton, one of its up quarks changes into a down quark, and a W- boson appears briefly, then transforms into a positron and an electron neutrino. If any of this sound familiar, it is because this is the mechanism behind beta decay. There are two kinds of beta decay (beta plus and beta minus), and you can review them and related material by using the links below to related questions.
What do quarks have to do with creating a beta particle?
Beta decay involves changing an up quark into a down quark (Beta+) or a down quark into an up quark (Beta-). This causes a neutron to change into a proton (Beta-) and emit a W- boson which decays into a beta particle (electron and electron antineutrino), or, with extra energy, it causes a proton to change into a neutron (Beta+) which emits a beta particle (positron and electron neutrino). Quarks are involved because protons and neutrons are comprised of quarks in sets of three, two up quarks and one down quark to form a proton, and two down quarks and one up quark to form a neutron.
What was the reactant that underwent beta decay if 14 7 N was the product?
7N14 is the product of beta- decay of 6C14. Remember, beta- decay involves changing a neutron into a proton, with the emission of an electron and an electron antineutrino. The W- boson is an intermediate product of the changing of a down quark to an up quark that is represented by the change of a neutron into a proton, which then decays into the electron and electron antineutrino pair.. In a nutshell, with beta- decay, atomic number goes up by one, and atomic mass number stays the same.
Which subatomic particle are charged?
Quarks, most particles made of quarks, leptons, and the W boson.
What type of radiation is emitted when carbon 14 is decays?
Carbon-14 decays by beta-, which emits a W- boson that immediately decays into an electron and an electron anti-neutrino.
What is the beta decay of radium?
226 Ra 88 ---> 225 Ac 89 +W boson W boson ---> e- + neutron
In beta decay what is emitted?
Beta- decay involves changing a neutron into a proton, with the emission of a W- boson, said boson then decaying into a electron and an electron antineutrino. Beta+ decay involves changing a proton into a neutron, with the contribution of energy, and then the emission of a positron and an electron neutrino.
What is a weak boson?
A boson responsible for carrying the weak nuclear force (responsible for beta decay). There are three different kinds W-, Z0, and W+ all rather heavy and acting only over short ranges.
What type of nuclear radiation is emitted when carbon-14 decay?
Yes, carbon 14 is a radioactive isotope.
What is a Z boson?
A Z boson is fundamental particle - a gauge boson which, together with the W boson, mediates the weak nuclear force. It has a charge of 0.
What is a Z-boson?
A Z-boson is a fundamental particle, a gauge boson, which, together with the W-boson, mediates the weak nuclear force, and has a charge of 0.
Atomic number increases by one during what type of radioactive decay?
Beta decays does. But alpha decay lowers it by 2.
What are the particular negative particles required to create beta particles?
For beta- decay, the resulting particles are an electron and an antineutrino. However, it is incorrect to say that these particles create the beta particle. It is more correct to say that the weak interaction causes a down quark in a neutron to change to an up quark, releasing a W- boson. The neutron becomes a proton, and the W- boson decays into the electron and the antineutrino. For beta+ decay, the resulting particles are a positron and a neutrino. It is a similar, though not quite the same reaction. Energy is absorbed, either from an energy rich nucleus, from electron capture, or from internal conversion, converting an up quark in a proton into a down quark, releasing the positron and neutrino, and changing the proton into a neutron.

What is a Z particle?
A Z particle is another name for the Z boson - a fundamental particle which, together with the W boson, mediates the weak nuclear force. It has a charge of 0.
What are the three particles released?
There are much more than three particles released in the various nuclear reactions. Off the top of my head, and probably not complete...Electron - from beta-Electron Antineutrino - from beta-W- Boson - intermediate from beta-Positron - from beta+Electron Neutrino - from beta+Helium Nucleus - 24He2+ - from alphaPhoton - from excited nucleus (various)Photon - from excited electron cloud (various)Neutron - from fission and other rareProton - from other rareOther nuclei - from various fission
