Radioactive Decay
Radioactive decay is a natural process where unstable atomic nuclei lose energy by emitting radiation, transforming into more stable forms. This can occur through several mechanisms, such as alpha decay (emitting helium nuclei), beta decay (converting a neutron into a proton), or gamma decay (emitting high-energy photons). Radioactive decay is fundamental to nuclear fission (splitting heavy atoms) and fusion (fusing light atoms) and plays a crucial role in nuclear astrophysics, explaining elements' formation in stars. Additionally, it impacts atomic structure by altering the number of protons and neutrons in the nucleus, leading to the formation of different elements and isotopes.

Radioactive decay is a natural process where unstable atomic nuclei lose energy by emitting radiation. Over time, a radioactive substance transforms into a more stable form. This process occurs at a predictable rate, characterized by a specific "half-life," which is the time it takes for half of the original substance to decay. The emitted radiation can be in the form of alpha particles, beta particles, or gamma rays. Radioactive decay is fundamental in fields like nuclear medicine, radiometric dating, and understanding nuclear reactions. It's a key process that helps scientists study the age of materials and track changes in elements over time.

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. This occurs as the nucleus transforms into a more stable state, releasing particles or energy in the form of alpha particles, beta particles, or gamma rays. Over time, this transformation results in the original element changing into a different element or isotope. The rate of decay is characterized by the half-life, which is the time it takes for half of a sample of the radioactive material to decay. This natural process is used in various applications, including medical imaging and dating ancient artifacts.
