The question cannot be definitively answered from the information given. It depends on the isotope what the decay modes are.
Brookhaven National Labs has an interactive chart of nuclides; you can click on a particular isotope and see the half-life and decay modes. I've put a link to it in the Related Links section.
Heavy nuclei typically emit alpha particles (composed of two protons and two neutrons) or beta particles (electrons or positrons) during decay as they seek to become more stable by reaching a more balanced ratio of protons and neutrons.
Alpha particles, protons, neutrons, electrons, neutrinos, nucleus of lighter elements, electro magnetic radiation and so on.
Yes, radioactive objects emit heat as a byproduct of their radioactive decay process. This heat is produced by the energy released during the decay of unstable atomic nuclei.
The spontaneous process in which unstable nuclei emit radiation is called radioactive decay. During this process, the unstable nucleus releases energy in the form of alpha particles, beta particles, or gamma rays in order to become more stable.
Radioactivity is the property in which unstable nuclei of an element spontaneously emit radiation.
In physics, radioactive refers to the property of certain nuclei to spontaneously decay and emit radiation in the form of alpha particles, beta particles, or gamma rays. This radioactive decay process results in the transformation of the nucleus into a more stable configuration.
Nuclear changes can occur through processes such as fission, fusion, and decay. Fission involves splitting heavy nuclei into smaller ones, releasing energy. Fusion combines light nuclei to form heavier ones, also releasing energy. Decay involves the spontaneous transformation of unstable nuclei into more stable ones, emitting radiation in the process.
The spontaneous process in which unstable nuclei emit radiation is called radioactive decay. During this process, the unstable nucleus releases energy in the form of alpha particles, beta particles, or gamma rays in order to become more stable.

This process through which unstable nuclei emit radiation is called radioactive decay. It also is called nuclear decay, and it is a natural process in which an atom of an isotope decomposes into a new element.
No, the fusion process is the opposite of the radioactive decay process. Fusion is the merging together of nuclei to form a heavier nucleus whereas fission or radioactive decay is the splitting apart of a heavy nucleus into lighter daughter nuclei.
K capture, a special case of inverse beta decay that doesn't emit a positron (but it does emit an electron neutrino)
Because the structure of their nuclei is unstable: too many or too few neutrons, excess energy causing metastable state, etc. To get more stable they decay, emitting alpha, beta, and/or gamma radiation.
The process you are referring to is nuclear fission. In this process, a heavy nucleus such as uranium-235 is bombarded with a neutron, causing it to split into two smaller nuclei, along with the release of one or two additional neutrons and a significant amount of energy. This chain reaction is the basis for nuclear power plants and nuclear weapons.
To become stable
Some isotopes emit an electron on decay, others emit a positron (anti-electron).
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
