Objective I- What causes change??

Interactions of particles in different parts of atoms cause many different changes. In reactions, such as nuclear or chemical, they are of one or more particles reacting with other particles to form completely new substances. Or in a thing like nuclear fission or fusion, two or more particles either break apart or come together to change the identity and some characteristics of the product. And finally, in isotopes, the rate of release either allows us to harness the change, or for the change to become an outrageous disaster. These are all just a few of the ways that change occurs in out world and in science.
