All isotopes of polonium can undergo alpha decay, a small number of isotopes can also undergo beta decay, K capture decay, or gamma decay.
There is no thallium-230 isotope.Also no thallium isotope decays by alpha decay, the unstable isotopes all decay either by K capture or beta decay.
Radium decays in any of (at least) four different ways, depending on isotope and, in some cases, on luck, as some isotopes can decay in different ways. The most important way radium can decay is by alpha emission. Nearly all naturally occurring radium decays this way, and so do the majority of synthetic isotopes. In this case, radium emits an alpha particle, which can be regarded as a helium nucleus, and the daughter atom is radon. The isotope of radon is depends on the isotope of radium involved; the mass number of the radon is always equal to the mass number of the radium minus four. Some heavier radium isotopes undergo negative beta decay, in which case the decay products are an actinium atom and a negative beta particle, which can be viewed as an electron. Some lighter radium isotopes undergo positive beta decay, in which case the decay products are a francium atom, a positive beta particle, which can be viewed as a positron, and an electron type antineutrino. A few radium isotopes also rarely undergo what is called cluster decay, and the most important naturally occurring isotope, radium-226 is among these. Cluster decay involves emission of a nucleus larger than an alpha particle, and in the case of radium all known cluster decays emit carbon-14 nuclei. In this case, the daughter atom is lead, with a mass number that is 14 lower than the mass number of the parent. So radium-226 can emit a carbon-14 nucleus, leaving a lead-212 atom.
Thorium-234 is not changed in uranium-234.- Th-234 is a decay product of U-238- By beta decay Th-234 is transformed in Pa-234
Forces do not decay.However the forces responsible for radioactive decay are: Strong - alpha & gamma, Weak - beta.The electromagnetic and gravitational forces do not participate in radioactivity at all.
No. Many atoms do not decay at all. Many that do undergo alpha decay. A few atoms emit neutron radiation.

No.
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.
As in all things, it will undergo decomposition and decay
I believe it has to do with fusion and fission, as all radioactive isotopes want to be as stable as possible.
It depends on which isotope you are asking about. Some decay through alpha, some decay through beta, some decay through other processes. All can leave the nucleus in an excited state, resulting in gamma emission.
Yes
The end point energy of a beta decay is the kinetic energy of all particles emitted through B-decay. This is often ignoring the energy of the recoiling daughter nucleus.
Because many radioactive elements undergo what is called a decay chain, or multiple decays until they finally become stable. For instance Thorium-232 undergoes a number of alpha and beta decays until it finally becomes stable as Lead-208. As such, while a compound may contain mostly Thorium-232, there may be a minute amount of other particles resulting from the decay of Thorium-232 producing different radioactive particles from Thorium-232. Another reason could be that certain radioactive particles can undergo more than one type of decay. For instance, Bi-213 can undergo either alpha or beta decay, and thus a sample of Bi-213 would emit both particles. Lastly, any particle that undergoes gamma decay will eventually undergo some other type of radioactive decay, since gamma ray emission does not actually change the atomic # of the element and thus does not make it eternally stable. Thus compounds producing gamma rays will always produce some other type of radiation as well, for instance Cobalt-60 produces gamma rays and beta particles
