These are released as radioactive particles (there are many types).
This decay process leads to a more balanced nucleus and when the number of protons and neutrons balance, the atom becomes stable.

But there are some questions that come to mind: Calculus students typically meet this problem somewhere in the second semester.
It is one of the simplest examples of a differential equation.
Imagine we have an undiscovered element, Parentium, that has a radioactive isotope, Parentium-123, which decays to stable Daughterium-123.
This is the only way Parentium-123 decays, and there is no other source of Daughterium-123.
Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.
Radioactive decay causes once-living specimens to lose half of their C14 atoms in about each 5,730-year half-life.
Thus, if the level today is half of what it was estimated to be when the thing died, it is said to be 5,730 years old.
This radioactivity can be used for dating, since a radioactive 'parent' element decays into a stable 'daughter' element at a constant rate.
The rate of decay (given the symbol λ) is the fraction of the 'parent' atoms that decay in unit time.
They are: (1) the C14 concentration in a specimen at its time of death; (2) the decay rate of C14; (3) the current C14 concentration in the specimen being “dated”; and (4) if anything else has affected the specimen’s C14 content. The curved line represents the declining amount of C14 atoms over time due to radioactive decay.
