Final thoughts on Atomic Structure and Radioactivity

In this unit we learned about what happens to atoms over time. We learned about three different scientists who contributed to our knowledge of atoms, Dalton, JJ Thompson, and Ernest Rutherford. They all conducted different experiments that helped to understand how atoms work. We also discussed radioactive decay and how it affects the nucleus of the atom.
