In simple words, Chemistry is the study of matter. In this branch of science, the properties, composition, structure, and transformations of matter are being studied in great detail. Because of this nature, the application of chemistry across different fields of study is immense.
Chemistry is often regarded as “the central science” because the knowledge obtained in chemistry is of high importance to students in various disciplines, including biology, medicine, geology, physics, and ecology, to name a few.
This reviewer will walk you through the introductory topics in chemistry. Specifically, you will learn more about atoms, the different states of matter, the periodic table of the elements, compounds, chemical and nuclear reactions, chemical kinetics, acids and bases, concentrations, thermochemistry, and a little bit about biochemistry, and organic chemistry.

Chemistry is the study of matter and the changes it undergoes. Anything that you can think about is probably made up of matter, and hence, can be studied in chemistry. In this section, we will discuss the properties, states, and types of matter. Click here to go to the article.
- Properties of Matter
- Types of Matter
- States of Matter
Understanding atoms is crucial because it ultimately leads to understanding why certain elements behave or react in a certain manner. In this section, we will study the atomic theory as well as the different atomic properties, components, and models. Click here to go to the article.
- Atomic Theory of Matter
- Atomic Models
- Components of an Atom
- Properties of an Atom
- Quantum Mechanics
- Electron Configuration
When you hear the word “Chemistry”, what comes to mind? There may be a lot of things, but one of those is probably the periodic table of the elements! In this chapter, we will talk about how elements are arranged in the modern periodic table, and what important properties and trends can we obtain from this arrangement.

- Brief History of the Periodic Table of Elements
- Groups and Families in the Periodic Table
- Periodic Trends
There’s no such thing as “chemical-free.” The water we drink and even the air we breathe are all considered “chemicals.” Learn more about “chemicals” and compounds in this section. Click here to go to the article.

We survive because of gases. Our atmosphere is composed of layers of gases, with the lowermost layer being the most suitable to support life. In this module, we will tackle the third state of matter, gases, and the laws governing their behavior. Click here to go to the article.
- The Concept of Ideal Gas
- Empirical Gas Laws
- Ideal Gas Equation
Two very dangerous elements, when combined together, can add flavor to the food you eat. This is all thanks to what we know as chemical reactions. Learn more about chemical reactions in this module. Click here to go to the article.
- Definition of Chemical Reactions
- Types of Chemical Reactions
- Balancing Chemical Reactions
- Reaction Stoichiometry: Limiting and Excess Reactants
Chemical reactions vary in the speed at which they occur, the study of which gave birth to a branch of chemistry called chemical kinetics. In this module, you’ll learn about the kinetics of chemical reactions, how to write rate expressions, and the methods usually used to determine reaction rates in a chemical laboratory.

- Writing Rate Law Expression
- The Method of Initial Rates
- Integrated Rate Law
Did you know that the majority of reactions are reversible, at least to some extent? In this topic, you will learn more about reversible reactions (aka equilibrium reactions). Click here to go to the article.
