Dalton's Atomic Theory correct answer: 1. Each element is composed of atoms 2. all atoms of a given element are identical all same in each individual element but no two elements are the same 3. Atoms can not be recreated by a reaction. Atoms can not be created or destroyed (law of conservation of mass) 4.

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...
