TExES Physical Science 6-12: Ionic & Covalent Bonds - Chapter Summary

Our experienced instructors make ionic and covalent bonds easy to understand with this handy chapter. Get ready to take the TExES Physical Science 6-12 exam by studying topics such as covalent, ionic, and polar covalent chemical bonds; the charge and formulas of ions; and reactions between ionic compounds. You'll also review writing ionic compound formulas and the properties and formation of covalent compounds. Once you finish this chapter, you should be able to:

  • Outline Lewis structures for single, double and triple bonds
  • Detail Lewis structures for polyatomic ions
  • Predict bond polarity and ionic character
  • Discuss VSEPR theory and molecule shapes
  • Explain dipole-dipole and ion-dipole forces and hydrogen bonding
  • Identify strong and weak intermolecular forces in London dispersion (Van Der Waals) forces
  • Predict molecular shape using orbital hybridization and valence bond theory
  • Diagram the molecular orbital theory

Help from an expert is just a few clicks away in the Dashboard if you struggle to understand any of these concepts. It's easy to navigate our videos using the timeline tags if you'd like to go back and review any of the material again. To make sure you're ready for exam day, take the quiz included with each lesson and the test at the end of the chapter.

Lewis Structures: Single, Double & Triple Bonds

8. Lewis Structures: Single, Double & Triple Bonds

Review what a Lewis dot diagram is and discover how to draw a Lewis dot structural formula for compounds. Learn how to represent single, double and triple bonds with lines instead of dots. Also, learn how compounds arrange themselves.

Lewis Dot Structures: Polyatomic Ions

9. Lewis Dot Structures: Polyatomic Ions

This lesson defines Lewis dot structures and explains how to draw them for molecules in step-by-step detail. We'll also explore polyatomic ions and how to draw Lewis dot structures for them.

Covalent Bonds: Predicting Bond Polarity and Ionic Character

10. Covalent Bonds: Predicting Bond Polarity and Ionic Character

Learn about covalent bonds and their two types: nonpolar covalent bonds and polar covalent bonds. Discover how to predict the type of bond that will form based on the periodic table. Learn what ionic character means and how to determine it.

VSEPR Theory & Molecule Shapes

11. VSEPR Theory & Molecule Shapes

In this lesson, you'll learn about the VSEPR theory and how it can be used to explain molecule shapes. Then, learn how to predict the shape of a molecule by applying the VSEPR theory to the Lewis dot structure.

Hydrogen Bonding, Dipole-Dipole & Ion-Dipole Forces: Strong Intermolecular Forces

12. Hydrogen Bonding, Dipole-Dipole & Ion-Dipole Forces: Strong Intermolecular Forces

Learn about intermolecular vs. intramolecular forces. Learn the different intermolecular bonds (including hydrogen bonding and dipole-dipole and ion-dipole forces), their strengths, and their effects on properties, such as boiling and melting points, solubility, and evaporation.

London Dispersion Forces (Van Der Waals Forces): Weak Intermolecular Forces

13. London Dispersion Forces (Van Der Waals Forces): Weak Intermolecular Forces
