Quizplus · Accepted Answer

A radionuclide is an atom whose nucleus is unstable and undergoes radioactive decay, releasing energy and particles in the process. This instability is caused by either having too many or too few neutrons in the nucleus, leading to an imbalance in the strong nuclear force that binds the nucleus together. Radionuclides are important in fields such as medicine, energy production, and nuclear weapons.
