CHEM101: General Chemistry I Saylor Academy

9 hours ago

1. Matter and Measurements. Chemistry is the study of matter and how we can change matter chemically and physically. What is matter? Matter is everything around us that has mass and volume.
2. The Atom. The atom is the basic unit of matter and serves as our starting point for the study of chemistry. The atom is composed of the subatomic particles protons, neutrons, and electrons.
3. Bonding. Bonds are connections between atoms. A solid grasp of valence shell electron pair repulsion (VSEPR) theory will help you understand how elements that differ by one or two atomic numbers behave.
4. Chemical Formulas and Equations. Chemists need to write out formulas and equations to solve chemistry problems. It is important that chemists have a common set of rules for writing formulas and equations so they can communicate with other scientists.
5. States of Matter. In this unit, we explore how matter behaves in terms of the three main phases of matter: solids, liquids, and gases. We investigate gases first because their properties are described by well-defined equations.
6. Thermochemistry and Thermodynamics. In this unit, we study thermodynamics and thermochemistry. Thermodynamics is the study of heat transfer. Thermochemistry is specifically the study of heat transfer in chemical reactions.
7. Acid-Base and Oxidation-Reduction Reactions. In this unit, we study two important types of chemical reactions: acid-base and oxidation-reduction.
8. Nuclear Chemistry. Finally, we'll examine the processes of nuclear decay, nuclear fusion, and nuclear fission. Unlike all other types of chemical reactions, which involve electrons, nuclear reactions involve the nucleus of the atom.
