How are isotopes created
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.
