The phrase which best describes nuclear fusion is: A. the process by which small nuclei combine into a larger nucleus.

A nuclear reaction can be defined as a type of chemical reaction in which the nucleus of an atom of a radioactive chemical element is transformed by either being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive chemical element and accompanied by a release of energy.

Generally, there are two (2) main types of nuclear reaction and these include:

  • Nuclear fission: it involves the collision of a heavy atomic nucleus with a neutron, thereby causing a split and release of energy.
  • Nuclear fusion: it involves the joining of two smaller nuclei of atoms to form a single massive or heavier (larger) nucleus with the release of energy.

In conclusion, nuclear fusion is best described as the process by which small nuclei combine into a larger nucleus, accompanied by a release of energy.
