WebHá 1 dia · The radioactive isotope forms continuously in the upper atmosphere as cosmic rays—high-energy particles from space—collide with gas molecules, spawning neutrons. When one of these neutrons knocks out a proton in a nitrogen atom, that nitrogen is transformed into 14 C. As it inhaled CO 2, the cedar had incorporated the 14 C into its … Some isotopes/nuclides are radioactive, and are therefore referred to as radioisotopes or radionuclides, whereas others have never been observed to decay radioactively and are referred to as stable isotopes or stable nuclides. For example, C is a radioactive form of carbon, whereas C and C are stable isotopes. There are about 339 naturally occurring nuclides on Earth, of which 286 are primordial nuclides, meaning that they have existed since the Solar System's formation.
