Radioactivity and Nuclear Reactions

Front

What is the primary process that powers the Sun?

Back

Nuclear fusion.

Front

What type of nuclear reaction occurs in a nuclear power facility?

Back

Nuclear fission.

Front

Define nuclear fission.

Back

A process where a big nucleus splits into smaller nuclei.

Front

What is the result of nuclear fusion in the Sun?

Back

Energy production.

Front

What is the role of neutrons in a fission reaction?

Back

They can strike other nuclei and cause a chain reaction.

Front

What is a chain reaction in the context of nuclear fission?

Back

A series of reactions where neutrons released from one fission event cause further fission events.

Front

How does the energy output of nuclear fusion compare to nuclear fission?

Back

Fusion releases more energy than fission.

Front

What are the byproducts of nuclear fission?

Back

Smaller nuclei (fission products), neutrons, and energy.

Front

What safety measures are important in nuclear power plants?

Back

Containment structures, control rods, and cooling systems.

Front

What is the difference between a controlled and uncontrolled chain reaction?

Back

A controlled chain reaction is used in reactors to produce energy, while an uncontrolled chain reaction leads to an explosion, as in a nuclear bomb.
