Nuclear Change

Nuclear change is distinct from chemical change (described in physical science topic 17 on this site). In a nuclear change the elements can change from one to another. An example of this is our own Sun. The Sun generates its energy by nuclear fusion changing hydrogen nuclei into helium. Nuclei can also break apart to form smaller elements (called fission). Nuclei can fuse together to make heavier elements. Neutrons can turn into protons and protons into neutrons.
