A common illustration that best describes radioactive decay is a graph depicting exponential decay, where the y-axis represents the quantity of a radioactive substance and the x-axis represents time. This graph typically shows a steep decline, indicating that the amount of the substance decreases rapidly at first and then more slowly over time. Additionally, a visual of a parent isotope transforming into a daughter isotope can effectively represent the process of decay and the concept of half-life, which is the time it takes for half of the radioactive material to decay.
Radioactive decay is the spontaneous breakdown of a nucleus into smaller parts.
The best definition of half-life for a radioactive substance is B. The amount of time required for half of the radioactive atoms to decay. This concept describes the time it takes for a given quantity of a radioactive isotope to reduce to half its original amount through the process of radioactive decay. Option A is incorrect because it inaccurately suggests that half-life refers to the time for all atoms to decay, which is not the case.

Because light waves and radioactive decay are some of the key factors that lead to the development of Quantum Mechanics. Quantum mechanics is also our best apparatus for describing and predicting those phenomena.
