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.

∙ 14y agoCarbon mainly exists as Carbon-12. Due to evolution Carbon-14 exists. It is present in very small amounts. Eg. If you take 1000 molecules, only 5 or 6 is Carbon-14.

Which isotopes combined during the sun's nuclear reactions and the element created?
Hydrogen isotopes(12H) and the element formed is helium(24He).
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.
How do you find the atomic weight on the periodic table?
On many Periodic Tables, the small number directly below the chemical symbol is the atomic mass. On mine, there is a small 12.011 under the large C for carbon. While most carbon is 12, there are naturally occurring carbon13 and carbon14, so this is an average mass of all naturally occurring isotopes, with the majority of isotopes being carbon12
What happens to the amount of nitrogen14 as the carbon14 decays?
Remains the same
How are istopes formed?
Isotopes are formed through variations in the number of neutrons in the nucleus of an atom
how isotopes are formed and what the example?
Isotopes are formed by nucleosynthesis.Uranium natural isotopes: U-234, U-235, U-238.
Which isotopes combined during the sun's nuclear reactions and the element created?
Hydrogen isotopes(12H) and the element formed is helium(24He).
What type of bond is formed between two isotopes of magnesium?
It would be a metallic bond as both isotopes are relatively strong metals.
What element is formed when neptunium desintegrates?
Neptunium-237 decay to protactinium-233.Other isotopes of Np decay to other daughter isotopes.

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.
