WebJun 9, 2024 · For example, uranium-238 is unstable because it spontaneously decays over time, but if a sample of uranium-238 is allowed to sit for 1000 years, only \(0.0000155\%\) … WebRadioactive Decay. Radioactivity is the phenomenon exhibited by an atom’s nuclei due to nuclear instability. In 1896, Henry Becquerel discovered this phenomenon. Radioactivity is a process by which the nucleus of an unstable atom loses energy by emitting radiation.
