What occurs during isotopic decay?

• A. An atom gains protons
• B. An atom changes from one isotope to another, often emitting radiation
• C. An atom loses electrons
• D. An atom doubles in mass

Answer: (B)

The process of isotopic decay involves a transformation of an atom from one isotope to another, which is typically accompanied by the emission of radiation. This is a fundamental aspect of radioactive decay, where unstable isotopes seek stability by shedding energy and particles. During this decay process, the nucleus of the atom undergoes a change—either by the release of a particle (like an alpha or beta particle) or by the emission of gamma radiation. This results in the formation of a different isotope, which can either be stable or may continue to decay further. This concept is crucial in understanding the behavior of elements over time, especially in fields like nuclear chemistry, medicine (for instance, in radioactive tracers), and geology (in radiometric dating). The other options are incorrect because isotopic decay does not involve gaining protons, losing electrons, or a doubling of mass; these processes are governed by different mechanisms in nuclear or atomic behavior.
