Introduction

Module 7—Investigating the Nature of the Atom

 

Module Introduction

 

In this module you will explore the early investigations related to the structure of matter. From investigations with cathode rays to the interaction of electromagnetic radiation and matter, these early experiments laid the foundation for our current understanding of the structure of matter.

 

The discovery of the electron and nucleus, as well as their physical characteristics, was critical to building an understanding of how the atom is modelled and organized. At the end of Module 7 you will understand the electrical nature of the atom and the quantization of energy in the atom and nucleus.

 

Specifically, you will be asked to apply your knowledge to answer the following question:
  • How does the quantization of energy in atoms and nuclei reveal the electrical nature of the atom?
