4.1: ATOMIC STRUCTURE Earlier in this course, we explored a very elementary view of atomic structure. We learned about protons, neutrons, and electrons (the three elementary particles that comprise an atom) and their properties. In this module, we will study these particles in detail and learn how their presence and arrangement determines the properties of all matter. The Electron During the 1800s, a number of scientists, including Sir Humphrey Davy, Michael Faraday, R. A. Milligan, G. J...
