The nuclei of a stable radioactive isotope will after been bombarded with a neutron produce a radiation and enormous energy and such reaction will come to an end, while the nuclei of an unstable nuclei will continue to react with little fragment of the neutron continuously (long chain nuclear reaction) until it has attain it stable phase.mind you this reaction with the little fragment of this neutron can last over 10 years.
Around 1500 unstable nuclei (or radioisotopes).

Radioactivity
Radioactive decay or radioactivity
The term is "radioactive decay".
Around 1500 unstable nuclei (or radioisotopes).

Eukaryotes have nuclei. In prokaryotes, the material that would be inside the nuclei is dispersed within the cell.

Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
The spontaneous decomposition of unstable atomic nuclei.
Radioactive decay
In most atoms the protons and neutrons found in the nucleus are held together strongly. The nuclei of these atoms are said to be stable. However, the neutrons and protons in some atoms are not held together as strongly. These nuclei are unstable and will eventually disintegrate, forming other elements. Isotopes that are unstable are said to be radioactive and are called radioactive isotopes or radioisotopes.
