What is the lightest element that can undergo radioactive decay and what type of decay occurs in that element?
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
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.
What is the nuclear decay equation for uranium-238 to strontium-90?
The equation for the beta decay of 87Kr is: 3687Kr --> 3787Rb + -10e where -10e represents a negative beta particle or electron.
What follows radioactive decay?
The final product is a stable isotope, but what it is depends on the decay. The intermediate steps constitute what is called a decay chain. For example, one well known decay chain is that of thorium-232, which goes through a series of radioactive isotopes decaying each to the next. The final product is lead-208, which stops the process since it is stable and does not decay further. Other decay chains produce other results. Sometimes the first decay produces a stable result, as in the case of tritium, which decays to helium-3.

What are the properties of radioactive decay?
Radioactive decay has the following properties: 1. No element can completely decay. 2. The number of atoms decaying in a particular period is proportional to the number of atoms present in the beginning of that period. 3. Estimate of radioactive decay can be made by half life and decay constant of a radioactive element.

All substances that naturally undergo radioactive decay do so until they finally become a stable isotope of one particular element what is the element?
The decay of radioactive substances follows a decay chain that will sooner or later result in the appearance of a stable isotope of lead. There is an exception for the atoms of a few substances that have undergone decay by spontaneous fission.

What is a by product of radioactive decay?
The 3 things that can happen during radioactive decay is the 3 parts of decay: Alpha decay, Beta decay, and Gamma decay. In alpha decay, which is the weakest part of decay, it has a positive helium neuclus(2 protons and 2 neutrons), and the particles will burn your skin, but can be easily stopped by a peice of paper. This is the most ionising as the helium nucleus can take electrons from other atoms and make them unstable. This can give rise to cancers as it distorts cells. In Beta decay (an electron or a positron) is emitted. In the case of electron emission, it is referred to as "beta minus" (β−). It can be stopped by 3mm of aluminum. Gamma decay, which is the strongest, can only be stopped by 3cm of lead. It has electromagnetic waves, it contains the most energy, and therefore is the most penetrating, but normally it just passes straight through the human body. Radioactive decay can be very harmful, and its best to stay away. This question has been anwsered by Rae-Ann Salisbury.
