Nuclear Applications notes and review

Multiple Choice

What are the key differences between fission and fusion in nuclear chemistry?

• Fission involves splitting atoms, while fusion involves combining them.

• Fission releases energy, while fusion does not.

• Fission occurs in stars, while fusion occurs in nuclear reactors.

• Fission is a natural process, while fusion is artificial.

Without the sun, life on earth would not exist. There would be no warmth, no plants, no animals, no night and day.

To power itself, the sun is constantly generating a nuclear reaction in its core, in which hydrogen nuclei are combined to form helium. This process is known as ​ ​ ​
