Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by …

Nov 11, 2025 · Radioactivity, property exhibited by certain types of matter of emitting energy and subatomic particles spontaneously. It is, in essence, an attribute of individual atomic nuclei.

Jun 10, 2025 · Radioactivity occurs when an atom has an excess of energy, mass, or both, making its nucleus unstable. To reach a lower, more stable energy level, it releases energy in …

May 30, 2021 · Radioactivity is the spontaneous emission of ionizing radiation from nuclear decay and reactions. The three main types of radioactive decay are alpha, beta, and gamma decay, …

Nov 29, 2025 · Radioactivity is used in many fields such as medicine, industry, and scientific research, but it must be handled carefully because it can be harmful in high amounts. Detailed …

As its name implies, radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it "wants" to give up some energy in order to …

These forces within the atom work toward a strong, stable balance by getting rid of excess atomic energy (radioactivity). In that process, unstable nuclei may emit a quantity of energy, and this …

Radioactive decay reveals a fundamental truth about matter: some atomic nuclei are inherently unstable, and over time they spontaneously emit particles or radiation to reach stability. This …

May 21, 2024 · Radioactivity is the process whereby unstable atomic nuclei release energetic subatomic particles or electromagnetic radiation (EMR). This phenomenon can cause one …

May 1, 2025 · This article will take you through the depths of atomic structure, the mechanics of radioactivity, the different types of decay, the history of its discovery, the technological and …
