Carbon 12 carbon dating Lantana cam girl
Keep in mind that during this process, not all of the mass is conserved.
The 'heavier' atom that is produced is actually lighter than the two individual pieces, which means that mass is lost.
Fossil fuels are really just dead organisms that once used the sun for energy and that have been under a great deal of pressure by being buried under rocks.
So, right now on Earth, we can't run our own nuclear fusion reactors, but we still rely heavily on the fusion reactions that take place on the sun.
Also, those neutrons that were ejected can be used to initiate several other fission reactions.
This 'domino effect' caused by the neutrons is called a chain reaction, and it can be responsible for keeping the reaction going for a long time.

After it dies, the stable carbon-12 remains, while the radioactive carbon-14 undergoes beta decay to turn into nitrogen.Because many things were once living organisms or were once made from living organisms, measuring the percentage of carbon-14 in an artifact is a very reliable way of being able to tell how old the artifact is.Our next application of nuclear chemistry is in medicine.Try It risk-free What can the sun do that we can't? Are radioactive isotopes helpful in the medical field?The answers to these questions can be found in this lesson on the applications of nuclear chemistry.
