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.The sun is essentially a fusion reactor creating energy by fusing hydrogen atoms together to form helium, and the sun is our primary source of energy.We use the sun's energy for solar power, photosynthesis, and even in the fossil fuels we burn.
Nuclear fission occurs when a heavier atom splits into smaller pieces.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.Radioactive isotopes are used to determine the age of old artifacts, diagnose disease, and treat certain types of medical conditions.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.
