How do radioisotopes behave over time?

The behavior of radioisotopes over time involves their transformation into different elements through a process known as radioactive decay. As radioisotopes emit radiation, they can change into other isotopes or entirely different elements, which aligns with the nature of their instability. This decay process is intrinsic to their properties, leading to the gradual reduction in the quantity of the original isotope as it transforms into more stable forms.

It is important to understand that radioisotopes do not remain constant; rather, they go through a series of decay events, ultimately resulting in more stable configurations. This characteristic of change directly contradicts the idea of them always staying the same. Additionally, while some radioisotopes decay rapidly, their behavior is not limited to a rapid decay rate alone; many can decay slowly over longer periods. Overall, they systematically change into other elements until reaching a stable state.
