Introduction

This lecture will cover the unique approach used in this course to the introduction of the fundamental concepts of Chemistry. The Concept Development Study approach was created, implemented, developed and refined at Rice over the course of more than twenty years. In this pedagogy, each new concept is developed from experimental observations and scientific reasoning. By contrast, most introductory Chemistry courses simply present each concept as an accepted fact, without foundation. This is why most Chemical concepts seem abstract and unapproachable. The CDS approach has been shown to more effective for most beginning students. I hope that this opening lecture will pique your curiosity about how you might learn Chemistry in a way which is more effective and more fun....

Atomic Molecular Theory and Atomic Masses

Chemistry can be understood fundamentally as the study of atoms and molecules. In this module, we will examine the experiments which reveal that all matter is composed of atoms which combine to form molecules. The clever analysis of these experiments illustrates scientific reasoning at its finest, allowing us to understand the existence and properties of particles which could not be directly observed. In addition, by measuring the relative masses of the different types of atoms, we can begin to predict the ratios of masses of reactants and products during a chemical reaction....

Structure of an Atom and the Electron Shell Model

Proving the existence of atoms and knowing that they combine to form molecules does not provide a means to predict how or why these atoms might combine. This requires greater detail about the structure and properties of individual atoms. In this module, we extend our understanding of atoms by making observations which reveal the internal structure of the atom including a model for the arrangement of the electrons around the atomic nucleus. ...

Electron Energies and Orbitals

The electron shell model does not account for all of the observable properties of atoms, including the energies and motions of electrons. In this module, we observe that these energies are quantized. We also observe behaviors which reveal the surprising fact that electron motion is described by waves or “orbitals” which provide the probability for the movement of the electrons about the nucleus. This module takes us into the strange world of quantum mechanics....

Bonding and Structures in Covalent Molecules

To understand the types of compounds which can be formed and the properties of those compounds, we have to understand how atoms bond together to form molecules. In this module, we develop a model for the bonding of non-metal atoms to non-metal atoms, called a covalent bond. The model can be used to predict which combinations of atoms are stable and which are unstable. Observations of the structures of the molecules lead to a model to understand molecular geometries and properties related to those geometries. From this, we build a foundation for understanding and predicting how molecular structure is related to molecular reactivity and function....
