Which energy is emitted by the nucleus of an atom?

Which energy is emitted by the nucleus of an atom?

• A. Nuclear energy
• B. Electrical energy
• C. Thermal energy
• D. Mechanical energy

Answer: (A)

Energy released from changes in the nucleus is nuclear energy. When a nucleus changes state—such as during radioactive decay or a nuclear reaction—it moves toward a more stable configuration and releases energy. This release often shows up as radiation, like gamma rays, or as kinetic energy of emitted particles. The other forms listed—electrical energy (energy of moving charges), thermal energy (related to temperature), and mechanical energy (motion or position of objects)—are not specifically produced by the nucleus in these processes. Hence, the energy emitted by the nucleus is nuclear energy.
