What is nuclear fission?

Back

Nuclear fission is the process in which a heavy nucleus splits into two smaller nuclei, releasing a large amount of energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What is radioactive decay?

Back

Radioactive decay is the spontaneous breakdown of an unstable atomic nucleus into smaller particles, accompanied by the release of energy.

Front

What is half-life?

Back

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

Front

What happens to the nucleus during fission?

Back

During fission, the nucleus becomes smaller as it splits into two smaller nuclei.

Front

What happens to the nucleus during fusion?

Back

During fusion, the nucleus becomes larger as two light nuclei combine to form a heavier nucleus.

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 is the significance of the energy released in fission and fusion?

Back

The energy released in fission and fusion can be harnessed for power generation, such as in nuclear power plants and hydrogen bombs.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (2 protons and 2 neutrons).
