Fusion & Fission

Front

What is nuclear fission?

Back

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of energy.

Front

What is an example of an uncontrolled fission reaction?

Back

Atomic Bomb.

Front

How does a chain reaction occur in nuclear fission?

Back

When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, causing them to split.

Front

What type of nuclear reaction occurs in nuclear power plants?

Back

Fission.

Front

What is nuclear fusion?

Back

Nuclear fusion is a nuclear reaction in which two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What is the primary fuel used in nuclear fission?

Back

Uranium-235.

Front

What is the difference between fission and fusion?

Back

Fission splits heavy nuclei into smaller ones, while fusion combines light nuclei to form a heavier one.

Front

What is a chain reaction?

Back

A chain reaction is a series of reactions where the products of one reaction initiate further reactions.

Front

What is the role of neutrons in nuclear fission?

Back

Neutrons initiate the fission process by colliding with and splitting the nuclei of atoms.

Front

What is radioactive decay?

Back

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