Fusion VS Fission

Front

What is nuclear fusion?

Back

A nuclear reaction where two lighter nuclei combine to form a heavier nucleus, releasing energy.

Front

What is nuclear fission?

Back

A nuclear reaction in which a heavy nucleus splits into two lighter nuclei, releasing energy.

Front

What is a chain reaction?

Back

A series of reactions where the products of one reaction initiate further reactions, commonly seen in nuclear fission.

Front

What conditions are required for nuclear fusion?

Back

Very high temperature and pressure are required for nuclear fusion to occur.

Front

What role do neutrons play in isotopes?

Back

Neutrons have a stabilizing effect on an isotope, helping to balance the repulsive forces between protons.

Front

What is the primary difference between fusion and fission?

Back

Fusion combines lighter nuclei to form a heavier nucleus, while fission splits a heavy nucleus into lighter nuclei.

Front

What is an example of a fusion reaction?

Back

The process that powers the sun, where hydrogen nuclei fuse to form helium.

Front

What is an example of a fission reaction?

Back

The splitting of uranium-235 nuclei in a nuclear reactor.

Front

What is the energy release in fusion compared to fission?

Back

Fusion typically releases more energy per reaction than fission.

Front

What is radioactive decay?

Back

The process by which an unstable atomic nucleus loses energy by emitting radiation.
