Web5 de set. de 2024 · Figure 17.1. c: A radioactive isotope of carbon (carbon-14) has six protons and eight neutrons. It decays to a stable isotope of nitrogen (nitrogen-14), which has seven protons and seven neutrons. Radioactive decay releases radiation. (The particular type of radiation that occurs in this example is called beta minus decay, β-.) WebRadionuclide. A radionuclide ( radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess nuclear energy, making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferred to one of its electrons to release it as a conversion electron; or used to create ...
