About This Chapter
Chemistry: Periodic Table, Formulas & Reactions - Chapter Summary
What are the types of chemical bonds? How are acids and bases measured? What are examples of different chemical reactions? These are among the facts you can expect to review when you access this chapter. Other lessons focus on chemical bonds, formulas and elements. After you have completed your study of this chapter, you should be able to:
- Discuss the organization of the periodic table and physical properties of the elements
- Define and provide examples of chemical formulas
- Compare ionic and covalent chemical bonds
- Understand the measurement of acids and bases
- List common types of chemical reactions
Expert instructors guide you easily through each topic, using definitions, examples and illustrations to support each lesson. Create a flexible and convenient study schedule with 24/7 access to video and text lessons. Use self-assessment quizzes to determine if you've retained what you need to know in one lesson before moving on to the next.
1. The Periodic Table: Properties of Groups and Periods
How is the periodic table like the map you used on your last road trip? In this lesson, you will be introduced to the periodic table, the road map of chemists. We will discuss how the elements are organized and how you can use this organization to identify some of their major physical properties.
2. Chemical Bonds: Ionic vs. Covalent
Atoms make up everything on Earth, and chemical bonds are what hold those atoms together. In this lesson, we'll discuss two very important types of chemical bonds: covalent and ionic.
3. What is a Chemical Formula? - Definition, Types & Examples
Chemical formulas provide a lot of information about chemical substances, such as how many and what atoms they are made of, as well as the way the atoms are arranged. In this lesson, we'll discuss the different types of chemical formulas.
4. Acids and Bases
Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.
5. Common Chemical Reactions and Energy Change
This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.
