Radioactivity and the Law of Decay
Radioactivity is a natural phenomenon in which an unstable atomic nucleus spontaneously emits radiation, such as alpha particles, beta particles, or gamma rays, resulting in a transition to a lower energy state. This process can cause the nucleus to decay into a stable atomic nucleus or ion.
The law of decay describes the exponential decay of a radioactive substance over time. This means that the number of radioactive atoms present in a given sample exponentially decreases over a period of time, with the rate of decay being proportional to the amount of radioactive material present.
Key Points:
Radioactivity is a natural phenomenon where unstable atomic nuclei spontaneously emit radiation.
The law of decay describes the exponential decay of radioactive substances over time.
The number of radioactive atoms present in a given sample exponentially decreases over a period of time.
Radioactivity can cause the nucleus to decay into a stable atomic nucleus or ion
