Nuclear Reactions: Explained

Nuclear reactions involve changes in the nucleus of an atom, leading to the transformation of one element into another. These reactions can release an enormous amount of energy and are the fundamental processes behind nuclear power and nuclear weapons. There are two main types of nuclear reactions: fission and fusion.

Fission

In fission, the nucleus of an atom is split into two smaller nuclei along with the release of energy and several neutrons. This process is the basis for nuclear power plants and atomic bombs.

Fusion

Fusion involves the combination of two light nuclei to form a heavier nucleus. This process powers the sun and other stars and has the potential to provide clean and abundant energy through controlled fusion reactions on Earth.
