Radioactive decay is the spontaneous change or disintegration of an unstable atomic nucleus as it transforms itself to lose energy. It does this by the release of either particulate radiation or electromagnetic radiation, or both. This atomic event is random and cannot be predicted, but by applying statistical principles to large numbers of a given radionuclide, an "average" decay time can be found, and we have the half-life. There are several different types of radioactive decay. They range from spontaneous fission to alpha decay, beta decay and a couple of others.
The spontaneous breakdown of a nucleus
Nuclear fusion and nuclear fission are processes that involve nuclear reactions but are not examples of radioactive decay. Chemical reactions, such as burning wood, do not involve nuclear processes and are also not examples of radioactive decay.
Before a radioactive atom ceases to undergo further radioactive decay, it must reach a stable configuration or decay into a non-radioactive isotope through the emission of particles or energy. This process continues until the atom reaches a state of stability where it no longer emits radiation.
If it is related to Nuclear studies, then the answer would be fusion.
That statement is not entirely accurate. Radioactive decay can involve the emission of alpha particles, beta particles (electrons or positrons), and gamma rays. Electrons can be involved in certain types of radioactive decay processes.
Radioactive decay is the spontaneous breakdown of a nucleus into smaller parts.

radioactive decay
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
All the decay chain isotopes are radioactive and toxic (excepting the last member which is non-radioactive but also toxic); you think probably to radium or polonium.
material of non-organic origin
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.

No. A stable nucleus can form. If the new nucleus is radioactive, then it will contiue to decay until a non radioactive nucleus is attained.
Decay energy is the energy that has been freed during radioactive decay. When radioactive decay is ongoing it drops off some energy by means of discharging radiation.
One reason is that radioactive decay heats the earths interior
