Web10 de abr. de 2024 · Isotopes are created through natural processes such as radioactive decay, cosmic ray interactions, and nuclear fusion reactions in stars. For example, carbon-14 is created in the Earth’s upper atmosphere when cosmic rays interact with nitrogen atoms. Isotopes can also be created artificially through nuclear reactions. Web23 de jun. de 2024 · How do you create an isotope? Isotopes can either form spontaneously (naturally) through radioactive decay of a nucleus (i.e., emission of energy in the form of alpha particles, beta particles, neutrons, and photons) or artificially by bombarding a stable nucleus with charged particles via accelerators or neutrons in a …
