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.

Carbon-14 isotopes are formed in the Earth's atmosphere when cosmic rays collide with nitrogen atoms, transforming them into carbon-14. This radioactive carbon is then incorporated into carbon dioxide and subsequently absorbed by plants during photosynthesis. Animals then consume these plants, incorporating carbon-14 into their tissues.

What element is formed when neptunium desintegrates?
Neptunium-237 decay to protactinium-233.Other isotopes of Np decay to other daughter isotopes.
How do scientistes determine how meteorites been have in space?
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.
When californium decays into Cm what is formed?
Each isotope has another type of decay but generally from californium are formed curium isotopes and an alpha particle.
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
How many protons neutrons and electrons are in carbon14?
7 protons, 7 neutrons and 7 electrons
how isotopes are formed and what the example?
Isotopes are formed by nucleosynthesis.Uranium natural isotopes: U-234, U-235, U-238.
How are istopes formed?
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.
Which isotopes combined during the sun's nuclear reactions and the element created?
In the sun's nuclear reactions, hydrogen isotopes combine to form helium-4. Specifically, two hydrogen-1 isotopes combine through a process called nuclear fusion to create a helium-4 atom, releasing energy in the form of gamma rays and neutrinos.

When neutrons are released from the nucleus it changes to what?
Isotopes of the element is formed when the number of neutron changes.
What elements are produced in the sun?
From hydrogen, isotopes of helium are formed through nuclear reactions.
When californium decays into Cm what is formed?
Each isotope has another type of decay but generally from californium are formed curium isotopes and an alpha particle.
What is the difference between radiogenic isotope and stable isotope?
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.
