WebTherefore, the half-life of this radioactive element is approximately 24.8 years. Step-by-step explanation. Radioactive decay is a process by which the atomic nucleus of an unstable atom loses energy by emitting ionizing particles or radiation. The rate of decay of a radioactive element is proportional to the amount of the element present. WebRead Edit View history Potassium-40 ( 40K) is a radioactive isotope of potassium which has a long half-life of 1.25 billion years.
