WebRadioactivity is the term used to describe disintegration of atoms. The atom can be characterized by the number of protons in the nucleus. Some natural elements are unstable. Therefore, their nuclei disintegrate or decay, thus releasing energy in the form of radiation. WebApr 12, 2024 · 1. Radioactivity and Half-Life Radioactivity is the process by which a nucleus of an atom emits radiation, and uranium was the first element discovered to be naturally radioactive. In 1896, French physicist Henri Becquerel discovered that it emits radiation, leading to radioactivity’s discovery.
