Which best describes this type of reaction?
makvit [3.9K]

Explanation:

There are two classes of nuclear reactions which are:

  1. Nuclear fission
  2. Nuclear fusion

In nuclear fission, a radioactive isotope which has a heavier nucleus spontaneously disintegrates(breaks up) into 2 lighter nuclei and several neutrons with a large release of energy.

A nuclear fusion occurs by the combination of small atomic nuclei into larger ones with the release of a large amount of energy.

I hope you can make the best choice from this explanation.
