What happens to the energy of a radioactive atom during radioactive decay?

During radioactive decay, a radioactive atom undergoes a process where its unstable nucleus breaks down into a more stable form. This process generally involves the release of energy in the form of radiation, which may include alpha particles, beta particles, or gamma rays.

The energy emitted during this decay process is often a result of the changes in the arrangement of subatomic particles within the nucleus. As the atom transforms into a different element or isotope, the overall energy level decreases, and this excess energy is released, often leading to various forms of ionizing radiation. This release of energy is a fundamental characteristic of radioactive decay, highlighting the transformation of mass into energy as described by Einstein’s equation, E=mc².

By understanding that radioactive decay is a process associated with the release of energy, it becomes clear that during this transition, the atom does not absorb heat, nor does its energy remain constant or transform into chemical energy. Instead, the energy released signifies a fundamental change in the atom's structure, leading to a more stable state.
