Fusion and Fission

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two smaller atomic nuclei combine to form a larger nucleus, releasing energy in the process.

Front

Where does fusion occur naturally?

Back

Fusion occurs naturally in the sun.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a large atomic nucleus into smaller nuclei, accompanied by the release of energy.

Front

What is a chain reaction in nuclear fission?

Back

A chain reaction occurs when neutrons emitted from a fission reaction strike other nuclei, causing them to split and release more neutrons.

Front

What is radioactive decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.

Front

What are the products of nuclear fusion?

Back

The products of nuclear fusion are larger atomic nuclei and energy.

Front

What are the products of nuclear fission?

Back

The products of nuclear fission are smaller atomic nuclei, neutrons, and energy.

Front

What is the role of neutrons in a chain reaction?

Back

Neutrons emitted during fission can initiate further fission reactions in nearby nuclei.

Front

What is the difference between fusion and fission?

Back

Fusion combines small nuclei to form a larger nucleus, while fission splits a large nucleus into smaller nuclei.

Front

What is the energy output of fusion compared to fission?

Back

Fusion typically releases more energy per reaction than fission.
