Thermochemistry: Chemistry is the study of both matter and energy.Chemical Bonds: The atoms in a molecule or compound are attracted and repelled with respect to each other in ways that determine the types of bonds they can form.Write balanced chemical equations to describe reactions.

Learn how to tell whether or not a reaction can occur and what the products of a reaction will be. Chemical Reactions & Equations: Just as atoms and ions combine in very specific ways, molecules and compounds react with each other in definite quantities.Find out how to predict how many of one type of atom or ion will combine with others. Chemical Formulas: Atoms and ions don't bond together randomly.Define these terms and learn how to perform calculations to express quantities.

A mole is a useful way of measuring an amount of atoms or larger components of matter.

Molecules, Compounds, & Moles: Atoms can be joined together to make molecules and compounds.

Learn about the parts of an atom and how to identify the different types of ions. Ions can be made up of one or more types of elements and carry an electrical charge.

Atoms and Ions: Atoms are single units of an element.

Find out what that table is, how it was designed, and how you can use it to make your study of chemistry much easier.

The Periodic Table: The periodic table is a way elements can be organized based on their similar properties.Learn what an element is and get facts for them. The Elements: Elements are basic building blocks of matter.Find out how to use the scientific method to collect data and design experiments. The Scientific Method: Scientists, including chemists, are systematic about the way they study the world.Units & Measurements: Get a handle on the metric system and the common units used in chemistry.Introduction to Chemistry: Learn about what chemistry is, what chemists do, and why you would want to study this science.It's a good idea to supplement textbook learning with experiments using a chemistry kit. While it's fine to learn chemistry principles online, be aware that the lab component is an important part of the science.Jumping into the middle of the science can lead to confusion. Chemistry concepts should be studied in a logical order because concepts build upon each other.It's possible to learn the basic concepts of chemistry online.
