Fission and Fusion

Front

What is nuclear fission?

Back

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts, releasing a large amount of energy.

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 for fusion reactions in the sun?

Back

Hydrogen atoms are the primary fuel for fusion reactions in the sun.

Front

Which process releases more energy: fission or fusion?

Back

Fusion releases more energy than fission.

Front

What is a chain reaction in nuclear fission?

Back

A chain reaction is a series of reactions where the products of one reaction initiate further reactions, leading to a rapid release of energy.

Front

What type of reaction is used in nuclear power plants?

Back

Nuclear fission is used in nuclear power plants to generate electricity.

Front

What is an example of a fission reaction?

Back

An example of a fission reaction is the splitting of Uranium-235 when it absorbs a neutron.

Front

What is the main difference between fission and fusion?

Back

The main difference is that fission splits heavy nuclei into smaller ones, while fusion combines light nuclei to form a heavier one.

Front

What are the byproducts of nuclear fission?

Back

The byproducts of nuclear fission include smaller nuclei (fission fragments), neutrons, and a large amount of energy.

Front

What conditions are necessary for fusion to occur?

Back

High temperature and pressure are necessary for fusion to occur.
