Chapter 5: The Modern Atomic Model
The 20th century was filled with accomplishments in scientific understanding. One of the greatest accomplishments was the development of the quantum mechanical model. Chapter 5 traces the discoveries that led to the model and the describes the relationship between the electronic structure of atoms and the properties of elements.
