Fission and fusion

Front

What is nuclear fusion?

Back

Nuclear fusion is a reaction in which two lighter atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Front

What is nuclear fission?

Back

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

Front

What type of reaction occurs in the sun?

Back

Nuclear fusion occurs in the sun, where hydrogen nuclei combine to form helium.

Front

What is released during nuclear fusion?

Back

Energy is released when very light nuclei fuse together.

Front

What is an example of nuclear fusion?

Back

An example of nuclear fusion is the fusion of hydrogen atoms to form helium in stars.

Front

What is the primary fuel for nuclear fusion in stars?

Back

The primary fuel for nuclear fusion in stars is hydrogen.

Front

What happens to the mass during nuclear fusion?

Back

During nuclear fusion, some mass is converted into energy, according to Einstein's equation E=mc².

Front

What is the difference between fission and fusion?

Back

Fission involves splitting a heavy nucleus, while fusion involves combining light nuclei.

Front

What are the conditions required for nuclear fusion?

Back

High temperature and pressure are required for nuclear fusion to occur.

Front

What is radioactive decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.
