Ch 20: Glencoe Physical Science Chapter 20: Chemical Bonds

About This Chapter

The Chemical Bonds chapter of this Glencoe Physical Science Companion Course helps students learn the essential physical science lessons of chemical bonds. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Chemical Bonds textbook chapter.

How It Works:

  • Identify the lessons in Glencoe Physical Science's Chemical Bonds chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the chemical bond topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • How molecules and compounds are built
  • The types of chemical formulas
  • The octet rule and Lewis structures
  • Covalent chemical bonds
  • Ionic chemical bonds
  • Polar covalent chemical bonds
  • Hydrogen chemical bonds

How Compounds and Molecules Are Built From Elements

1. How Compounds and Molecules Are Built From Elements

Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.

The Octet Rule and Lewis Structures of Atoms

2. The Octet Rule and Lewis Structures of Atoms

Learn the octet rule and how it applies to electron energy levels. Identify valence electrons and learn how to determine them by looking at the periodic table. Also, discover how they pertain to the octet rule. Learn how to draw the Lewis diagram of an atom, and understand how it provides clues to chemical bonding.

Chemical Bonds I: Covalent

3. Chemical Bonds I: Covalent

Mom always said that sharing is caring. This lesson will explore how electrons affect the chemical reactivity of atoms and specifically the merits of sharing electrons.

Chemical Bonds II: Ionic

4. Chemical Bonds II: Ionic

Did you know that the scientific name for table salt is sodium chloride? Find out how sodium and chlorine atoms come together to form your favorite seasoning.

Chemical Bonds III: Polar Covalent

5. Chemical Bonds III: Polar Covalent

Are you confused about how you can tell what kind of bond two atoms will form? This lesson will help you understand the difference between polar and nonpolar covalent bonds as well as how to predict how two atoms will interact.

Chemical Bonds IV: Hydrogen

6. Chemical Bonds IV: Hydrogen

This lesson defines and discusses important concepts behind hydrogen bonding. You'll learn when and why these bonds occur and which atoms are often involved.

Naming Ionic Compounds: Simple Binary, Transition Metal & Polyatomic Ion Compounds

7. Naming Ionic Compounds: Simple Binary, Transition Metal & Polyatomic Ion Compounds

An important part of dealing with chemical compounds is knowing how to refer to them. Learn how to name all ionic compounds, including simple binary compounds, compounds containing transition metals and compounds containing polyatomic ions.

Covalent Compounds: Properties, Naming & Formation

8. Covalent Compounds: Properties, Naming & Formation

Learn about covalent bonds, how covalent compounds are formed and the properties inherent to covalent compounds, such as low melting and boiling points, in this lesson. Also, learn what rules to follow to name simple covalent compounds.
