What is nuclear decay?

Back

Nuclear decay is the process by which an unstable atomic nucleus loses energy by emitting radiation, resulting in the transformation of the nucleus into a different element or isotope.

What is fission?

Back

Fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of energy and radiation.

What is fusion?

Back

Fusion is the process in which two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy, as occurs in stars.

What is alpha radiation?

Back

Alpha radiation consists of helium nuclei (two protons and two neutrons) emitted from a radioactive source, and it has low penetrating power.

What is a chain reaction?

Back

A chain reaction is a series of reactions where a reactive product or by-product causes additional reactions to occur, commonly seen in nuclear fission.

What is the difference between fission and fusion?

Back

Fission is the splitting of a heavy nucleus into smaller nuclei, while fusion is the combining of light nuclei to form a heavier nucleus.
