Does a free neutron decay into a hydrogen atom?
A free neutron actually decays into a proton, and an electron and an antineutrino are ejected in the process. This is beta minus decay, and a free neutron is unstable and will decay by this mechanism. While it is true that a proton and an electron make up a hydrogen-1 atom, the decay of the neutron is slightly different. The reason is that the electron leaves the decay event with a high kinetic energy, and it cannot be "held" by the proton (to create the hydrogen atom). Certainly the proton will "pick up" an electron from somewhere after is slows down a bit following its creation, as it, too, has some kinetic energy. The proton will have to release that kinetic energy through scattering, just like the electron that left the event. Links can be found below to related questions with descriptive answers.
What are the steps of radioactive decay through which a beta particle is released?
Beta decay is a type of radioactive decay that comes in two types. The beta plus decay and beta minus decay can be described by use of an equation that places an unstable atom on one side and the products of the beta decay on the other. The beta minus decay of carbon-14 is just a single example of this equation, and here it is: 614C => 714N + e- + ve To learn more about beta decay, use the link below to the related question, "What is beta decay?"
What does the half life of a radioisotopes indicate?
The half life of a radioisotope indicates the rate of decay for a radioactive sample
Discuss with the use of examples the main differences between alpha and beta decay?
In alpha decay, an alpha particle (a helium nucleus - 2p+ and 2n0) is emitted from the nucleus of an atom. In beta decay, a neutron turns into a proton and an electron, and the electron (beta particle) is emitted from the nucleus of the atom.
An atom of 134 84 PO decays by alpha decay Which atom is left after the decay?

Is the atom left after decay often radioactive?
Yes, the atom left after decay is often radioactive because the decay process can lead to the creation of unstable isotopes that emit radiation. This radiation can continue to decay until a stable atom is formed.
What are the changes to the atom during gamma radiation?
Gamma emission is not a decay process. It is a restabilization process of the nucleus in response to some other decay process, such as alpha or beta, which leaves the nucleus in an excited state. When the nucleus comes down from that excited state it emits a photon of energy equal to the step change in energy that was made. Short answer: The atomic mass or atomic number of a nucleus is not changed, specifically, by the gamma emission, but it is changed by the precipitating alpha or beta (or other) event that left the nucleus in an excited state. Slightly more correct answer: The mass of the nucleus is decreased by the equivalent mass of the loss of energy that occurs. This ratio is e=mc2, where c2 is 9 x 1018, so you can see that the delta mass due to gamma emission is very, very small.
What happens to radioactice substances when they decay?
The atom that decays leaves emits some radiation, and leaves behind another type of atom (or atoms), with less mass (the mass of the original atom, minus the mass that left the atom). There are several common types of radioactive decay. In alpha decay, an alpha particle is emitted. This is two protons and two neutrons bound together. In beta decay an electron or positron is emitted. Excited nuclei may shed their excess energy by emitting a neutral gamma ray. Some nuclei even emit neutrons (the fission products in a nuclear reactor are especially prone to this). And sometimes the nucleus may grab an orbiting electron in "K-capture". Some of these events alter the nucleus's charge thus changing it into a different chemical element. In addition, the proton-to-neutron balance may be changed enough to make the new nucleus unstable so it decays again. In most cases the decay leaves the nucleus in an excited state which may destabilise it resulting in further decay too. It is not uncommon for a material to decay through several generations at hugely different rates. But eventually the nucleus settles down as a different chemical element, the orbiting electrons re-shuffle and, well, that's it. The substance therefore changes into another one. Since the processes are very specific for every isotope, the composition of an old rock, for example, can give us complete information about what was in it a thousand, a million, a billion years ago.
Does a radioactive isotope decay at a varying rate from the time it forms?
The probability of decay of any particular atom is a constant. However, as time passes, the there are fewer atoms left to decay. So in that respect the number of decay event falls.
What happens to a radioactive material over time?
It disintegrates into its daughter nuclei that are much more stabler than the radioactive nuclei. If a sample of radioacictive material is left it will decay into another element over a period of time. Note that complete decay is not possible. A fraction of the original radioactive material will always remain in the sample.

Will the decay product ever rach to 100?
I assume you mean, that 100% of a product decays. In radioactive decay, in purely mathematical terms, this will never happen; but for practical purposes, after several half-lives elapse, the amount of remaining substance (of the original substance) is so small as to be insignificant for most practical purposes. Also, since a material is made up of individual atoms, the time will come when (once again, in a purely mathematical way) much less than one atom is left; what this means in practice is that the probability of even one atom being left becomes insignificant.
An atom 134 84Po of decays by alpha decay Which atom is left after the decay?
Since an alpha particle contains 2 neutrons and 2 protons (for a total of 4 nucleons), you are supposed to subtract that from the nucleus. In other words, you will get isotope 171 76 (4 nucleons less, 2 protons less). APEX 171 76 Os

When radioactive decays stop?
It will stop when there is nothing left to decay. There is basically no way to stop certain nuclides (isotopes) from decaying.
