Carbon-14 is produced in the upper atmosphere when cosmic rays produce thermalised neutrons, by hitting atomic nuclei. If these thermalised neutrons then hits a Nitrogen neuclei it creates Carbon 14.
Neptunium-237 decay to protactinium-233.Other isotopes of Np decay to other daughter isotopes.
By looking at radioactive isotopes. These isotopes decay at precisely known rates, so looking at ratios involving such isotopes can tell when an asteroid or other object formed.
Each isotope has another type of decay but generally from californium are formed curium isotopes and an alpha particle.
Carbon14 dating (isotopic dating)
Carbon-14 has 6 protons. The number of protons in an element's nucleus determines its atomic number, and for carbon, this is always 6, regardless of the isotope. Carbon-14 is a radioactive isotope of carbon, differing from the more common carbon-12 and carbon-13 isotopes by having 8 neutrons.
Isotopes are formed by nucleosynthesis.Uranium natural isotopes: U-234, U-235, U-238.
Isotopes are formed through processes like radioactive decay, where a nucleus gains or loses protons and neutrons to become a different element. Isotopes can also be formed through nuclear reactions, such as fusion or fission, which change the composition of the nucleus. The different number of protons or neutrons in isotopes gives them unique properties and varying stability.

From hydrogen, isotopes of helium are formed through nuclear reactions.
Isotopes of the element is formed when the number of neutron changes.
Radiogenic isotopes are formed through the radioactive decay of parent isotopes, while stable isotopes do not undergo radioactive decay. Radiogenic isotopes are used in geochronology to date rocks and minerals, while stable isotopes are used in various fields such as climate science and nutrition studies.
Each isotope has another type of decay but generally from californium are formed curium isotopes and an alpha particle.
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
