This makes the already slightly unstable heavy atom even more unstable, which causes it to split into smaller atoms and possibly eject a few neutrons.This releases a lot of energy because the original atom was so unstable.While an organism is living, it has a set ratio of carbon-14 to carbon-12.After it dies, the stable carbon-12 remains, while the radioactive carbon-14 undergoes beta decay to turn into nitrogen.Now, carbon-14 has a half-life of about 5,730 years, so every 5,730 years, half of it is going to decay into nitrogen.The more carbon-14 that an artifact has, the more recent it is.Free 5-day trial What can the sun do that we can't? Are radioactive isotopes helpful in the medical field?

In this lesson, we are going to take a closer look at each of these applications of nuclear chemistry. The answer is 'run on nuclear fusion.' Nuclear fusion occurs when two or more atoms fuse together to form a single, heavier atom.Sometimes when diagnosing certain types of diseases, stable atoms in your body are replaced by radioactive atoms of the same element.These radioactive elements then move around throughout your body as they would normally, but because they are radioactive, they're easier to detect outside of the body.Carbon is an essential element for living organisms that are constantly exchanging carbon, most of which is carbon-12.

Some of those carbon atoms, though, are carbon-14 isotopes.

Nuclear chemistry is a field of chemistry that deals with the use of radioactive isotopes and other nuclear reactions.

Spill, what don't you like about them? When hiking alone at the top of an Alaskan mountain and the make-up team has put me through the works to look like I'm on the brink of death, I though it was an appropriate excuse to take a selfie. … continue reading »
