The proton takes an electron with it and becomes an atom of hydrogen. Usually a proton is knocked out of the nitrogen atom’s nucleus and is replaced with the neutron. This collision is less destructive than the initial collision that produced them. Some of these neutrons then collide with nitrogen atoms. Some fragments produced in this way are neutrons. When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart.
Cosmic rays are atomic nuclei from outside our solar system, moving at enormous speeds. The r adioactive carbon (Carbon-14, aka 14 C ) is a carbon isotope usually formed in the upper atmosphere as a byproduct of cosmic radiation. This energy release is called radioactivity. Th is excess of neutrons compared to protons in the atom make it un stable, so it will break down, releasing nuclear energy. 1 The radioactive carbon also has six protons, which makes it function as carbon, but it has eight neutrons in its nucleus, giving it a total atomic mass of 14. It is a stable, non-radioactive atom that will not change its atomic mass under normal circumstances. The normal carbon atom has six protons and six neutrons in its nucleus, giving a total atomic mass of 12 (Carbon-12, usually abbreviated to 12 C). Radiocarbon dating compares the amount of normal carbon with the amount of radioactive carbon in a sample. How does radioactive carbon dating work? What are its limitations? What effect would the declining strength of the earth’s magnetic field and a catastrophic worldwide flood have on radiocarbon dates? These are all questions that need to be examined carefully. These dates are often claimed to be very precise. Radiocarbon dating is frequently used to date ancient human settlements or tools.
