Nuclear Energy

Front

What is nuclear fusion?

Back

Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process. It occurs naturally in stars, including the sun.

Front

Where does nuclear fusion primarily occur?

Back

Nuclear fusion primarily occurs in the cores of stars, including our sun.

Front

What is produced when hydrogen undergoes fusion?

Back

Helium is produced when hydrogen undergoes fusion.

Front

What is nuclear fission?

Back

Nuclear fission is a process where a heavy atomic nucleus splits into two or more lighter nuclei, along with the release of energy.

Front

What fuel is commonly used in nuclear power plants?

Back

Uranium is commonly used as fuel in nuclear power plants.

Front

What is a half-life?

Back

A half-life is the time required for half of the radioactive atoms in a sample to decay.

Front

How does the half-life of an element relate to its radioactivity?

Back

The longer an element's half-life, the longer it will take to decay, indicating it is less radioactive.

Front

What is the main difference between nuclear fusion and nuclear fission?

Back

Nuclear fusion combines light nuclei to form a heavier nucleus, while nuclear fission splits a heavy nucleus into lighter nuclei.

Front

What are the byproducts of nuclear fission?

Back

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

Front

What is the role of neutrons in nuclear fission?

Back

Neutrons can initiate further fission reactions by colliding with other heavy nuclei, leading to a chain reaction.
