Radioactive Element

A radioactive element is an element with unstable atomic nuclei that undergo radioactive decay.  This decay process involves the emission of particles or electromagnetic radiation from the nucleus, leading to a transformation of the nucleus into a more stable state.  The elements that exhibit this behavior are called radioactive isotopes or radionuclides.  Radioactive decay can result in the emission of various types of radiation, including alpha particles (helium nuclei), beta particles (electrons or positrons), and gamma rays (electromagnetic radiation).  The decay process continues until the nucleus reaches a stable configuration.

The radioactive properties of certain elements have important applications, such as in nuclear power generation, medical diagnostics and treatment, and scientific research.  However, exposure to high levels of radiation can be hazardous to human health, and proper safety precautions are essential when working with or near radioactive materials.
