Step 4: Summarize nuclear changes.
a) Use your completed table and models to write a summary that addresses the following questions:
1. How does energy change in these reactions? Is energy needed to start the reactions or is energy given off in the reactions? For each type of reaction, approximately how much
energy is released?
2. How do these energy changes compare in scale to other types of reactions, such as chemical reactions?

Nuclear changes involves changes in the composition of the nucleus of atoms with the release of large amounts of energy.

What are nuclear changes?

Nuclear changes are changes which occur in the nucleus of atoms of elements.

Nuclear changes involves radioactive decays to give radiation and energy spontaneously known as radioactivity.

In this type of nuclear change no energy is required to start the reaction but large amount of energy are released.

Nuclear changes can also involve splitting of large nucleus into smaller nucleus of atoms known as nuclear fission or the formation of larger nucleus from the combination of two or more smaller nuclei known as nuclear fusion.

Energy is required to start nuclear fission and fusion but the energy released is far greater.

When compared with energy changes in chemical reactions, the energy released in nuclear reactions is far greater.

Therefore, nuclear changes involves changes in the composition of the nucleus of atoms with the release of large amounts of energy.
