Fusion vs Fission

Front

What is nuclear fission?

Back

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

Front

What is nuclear fusion?

Back

Nuclear fusion is the process of combining two light atomic nuclei to form a heavier nucleus, releasing energy in the process.

Front

What is a chain reaction in nuclear fission?

Back

A chain reaction occurs when the neutrons released from a fission reaction cause additional fission events in nearby nuclei.

Front

What is the primary difference between fission and fusion?

Back

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

Front

What is the role of neutrons in nuclear fission?

Back

Neutrons are emitted during fission and can initiate further fission reactions in other nuclei.

Front

What is the energy-matter relationship in nuclear reactions?

Back

In nuclear reactions, a small amount of matter can produce a large amount of energy.

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 an example of a fusion reaction?

Back

An example of a fusion reaction is the process that powers the sun, where hydrogen nuclei combine to form helium.

Front

What are isotopes?

Back

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons.

Front

What is the significance of mass-energy equivalence in nuclear reactions?

Back

Mass-energy equivalence, expressed by E=mc², indicates that mass can be converted into energy during nuclear reactions.
