Does silicon undergo radioactive decay?
The 3 isotopes that make up all naturally occurring silicon (28, 29, 30) on earth are all stable and thus do not undergo radioactive decay. But other silicon isotopes that are lighter or heavier can be produced by particle accelerators, nuclear reactors, nuclear explosions, or rarely cosmic rays do undergo radioactive decay via either -Beta, +Beta, or Gamma emission depending on isotope.Silicon does exist in space near very active stars, supernovas, etc. in the form of isotopes that undergo radioactive decay.The longest lived silicon isotope (32) that will undergo radioactive decay, has a halflife of roughly 700 years and thus will effectively completely decay to stable sulfur-32 in less than 4000 years. All other silicon isotopes that undergo radioactive decay have halflives so short that they finish decaying to stable isotopes of other elements in much less than a single day.
Is the weak nuclear force associated with nuclear decay?
(Warning: This is a little long. For a summary, scroll down to the bottom.)Depends on the kind of decay. There are many different types of possible nuclear decays:Alpha decay (throwing off helium-4 nuclei)Beta-minus decay (converting neutrons to protons, releasing electrons)Beta-plus decay (converting protons to neutrons, releasing positrons)Gamma decay (emission of high-energy photons after alpha or beta decay)Electron capture (an electron falls into the nucleus, converting protons to neutrons without releasing positrons)Spontaneous fission (the nucleus suddenly splits in two)Proton decay (a lone proton is thrown off)Neutron decay (a lone neutron is thrown off)9Of all of those decays, beta decays and electron capture involve the weak nuclear force.Deep inside of a proton or neutron, there are 3 fundamental particles named "quarks". In atomic nuclei, there are two kinds of quark: up and down. Up quarks have a charge of +2/3, while down quarks have a charge of -1/3 (yes, quarks have fractional charges.) Because of the strong nuclear force, quarks must gather into groups of 3.A proton contains two up quarks and one down quark. Two up quarks (charge +4/3) and one down quark (charge -1/3) add up to the proton's net positive charge of +3/3.A neutron contains two down quarks and one up quark. We'll let you do the math on this one, but they ultimately balance out to 0. Neutrons are heavier than protons, and, given the opportunity, they will spontaneously transform into a proton, throwing off an electron to balance the charges. A mysterious particle called an "antineutrino" is emitted (more on antineutrinoes later). This is caused by a down quark turning into an up quark via the weak nuclear force.Beta-minus decay is simply when a neutron in a nucleus is converted into a proton, throwing off a high-energy electron. This electron is our beta-minus particle.Beta-plus decay does not normally occur, because protons are lighter than neutrons, so they should not decay. But, in some particularly light nuclei, e.g. carbon-11, there is enough energy for a proton to transform into a neutron. This produces a high-energy particle called a positron. Positrons are basically electrons with a positive charge, instead of a negative one. A neutrino is also produced, more on these later. This is also governed by the weak nuclear force.Electron-capture occurs in the same nuclei beta-plus decay can take place in. We'll use potassium-40 as our example. K-40 can either undergo beta-plus decay, or, there is a slighter chance one of its protons will "capture", or consume, one of its electrons. This converts the electron into a neutrino, while satisfying the nucleus, which transformed from potassium-40 into stable argon-40.Neutrinoes are very evasive particles. They do not interact electromagnetically, hence the name, which means "small neutral one" in Italian. They are almost massless, and for a while, it was believed they were. Neutrinoes were first theorized in 1930 to explain why beta particles often had different energies, but were only found in 1955. Neutrinoes only interact via the weak nuclear force. They mainly serve a purpose as satisying the balance. There are also antineutrinoes, which are almost identical to normal neutrinoes, except for their position on the balance, explained below.This balance is of something called "electron number". You see, in a nuclear reaction, the total number of electrons involved must be conserved, both before and after the reaction. Electrons and neutrinoes have an electron number of +1. Positrons and antineutrinoes have an electron number of -1. In beta-minus decay, we start with a neutron (electron number 0). It turns into a proton (also electron number 0), producing an electron (electron number +1) to conserve charge. In order to satisfy the balance and conserve electron number, an antineutrino (electron number -1) is released. Neutrinoes have no electrical charge, so both charge and electron number are balanced.Alpha decay, gamma decay, and spontaneous fission do not rely on the weak nuclear force. Alpha decay is when a helium nucleus manages to escape the nucleus. Proton and neutron decay work in similar manners. Gamma decay is when nucleons leaving produces holes in lower-energy states, which higher-energy nucleons move into, releasing the energy in a high-energy photon. Spontaneous fission also works similarly to alpha decay: in fact, alpha decay is a version of spontaneous fission!So, to answer your question simply, some decays are associated with the weak force, some aren't. Depends on which decay you're talking about.
When is Ronnie Radke from Escape The Fate getting out of jail?
he did get out of jail then he was just on probation for five years but he got sent back to jail for missing it, wich sucks anyway 'cause escape the fate already has a new lead singer Craig mabbit via lead x-lead singer of blessthefall but it dosent matter because he has formed a new band called from behind these walls and its going pritty well for him.

Africa, via the American South.
What is the product of the beta decay of bismuth?
It depends on which isotope of bismuth we are talking about. Most isotopes less than bismuth-209 that decay by beta do so via beta+, and they decay to lead, while most isotopes greater than bismuth-209 that decay by beta do so via beta-, and they decay to polonium.There are some isotopes that decay by other mechanisms, such as alpha, but the question asked only about beta.

Tritium (3H) decays into 3He via beta decay.
What is the equations for the beta decay of radon-198?
Radon-198 does not decay via beta decay. It is thought to decay by alpha decay, but that is not certain. The equation would be ... 86198Rn -> (Alpha, T1/2 = 86 ms) -> 84194Po + 24He2+
What is the charge of an alpha decay?
The weak nuclear force is responsible for all particle decay. In a neutron, there are two down (d) and one up (u) quars with charges of -1/3 and +2/3, respectively. In a proton, there are two up and one down quark. The configuation looks like this: N: udd P: uud One of the down quarks in the neutron changes into an up quark (via the W- particle) and an electron. The neutron is now a proton.
How do pions decay into muons?
Negatively charged pions decay into muons and muon anti-neutrinos via the weak nuclear interaction. The probability of such a decay occurring is approximately 99.98%. Muons can also decay into electrons and electron anti-neutrinos, but the probability of such a thing occurring is only about 0.012% Positively charged mouns decay into anti-muons and muon neutrinos instead. Neutral pions decay into either two photons or a photon and one electron and one positron. One decay of a negatively charged pion produces one muon and one muon anti-neutrino.
How is uranium-238 converted to plutonium-239?
Each isotope of plutonium has its own decay scheme. Plutonium-239 is the most widely used isotope, and it undergoes alpha decay into uranium-235 with a half-life of 2.41 x 104 years (24,100 years). A link is provided to the Wikipedia article on plutonium.
What is the nuclear equation for decay of tin-122 with the emissions of beta particles?
From the Wikipedia article in tin isotopes, it seems that tin-122 is "observationally stable", meaning that it has not been observed to decay. The article also states that it is believed to decay via beta- beta- decay, into tellurium-122. This type of decay - if it really exists - would have to be extremely slow, if it hasn't been observed yet. Since tellurium has 2 more protons than tin, and the total number of nucleons is the same (122), it follows that the end-product would have 2 neutrons less.

When did the protosun become the sun?
No our Sun is a fully formed Star. A Protostar is gas that is still acreeting matter (still collecting via gravtaional rotation) to form a star. And as a result they are not very bright as they have not condensed enough to start Nuclear Fusion.
