Before, during or after reviewing the lessons, you can take self-assessment quizzes to gauge how well you understand chemical bonding. If you answer any questions on the quizzes incorrectly, simply click the link next to that answer to revisit the related portion of the video. A chapter exam is also available to assess your readiness to take the MEGA assessment. Any questions about lesson topics can be submitted to our experts.
1. 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.
2. Ions: Predicting Formation, Charge, and Formulas of Ions
Learn how ions are formed using the octet rule. Use the periodic table to predict the charge an atom will have when it becomes an ion. Learn whether an ion is a cation or anion and how to write the formula depending on what charge the ion has.
3. Ionic Compounds: Formation, Lattice Energy and Properties
In this lesson, you'll learn about ionic compounds and how they form. Additionally, you'll learn the properties of ionic compounds, such as their high melting and boiling points, their ability to conduct electricity, and the fact that they form crystals.
4. 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.
5. 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.
6. 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.
7. Lewis Dot Structures
Although drawing dots around elements sounds pretty straight forward, Lewis dots are a little more complicated. This lesson will explain how to draw Lewis dots for single, double, and triple bonds, as well as polyatomic ions.
8. 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.
9. 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.
10. 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.
11. London Dispersion Forces (Van Der Waals Forces): Weak Intermolecular Forces
Learn how London dispersion forces are created and what effect they have on properties such as boiling and melting points. Discover this weak intermolecular force and how it is one of the Van der Waals forces.
12. Using Orbital Hybridization and Valence Bond Theory to Predict Molecular Shape
You'll learn how to explain how shapes of molecules can be predicted using valence bond theory and hybridization. When finished, you'll understand the difference between sigma and pi bonds and how the VSEPR theory, along with the hybridization theory, helps predict the shape of a molecule.
13. Molecular Orbital Theory: Tutorial and Diagrams
Learn how to sketch the overlap of orbitals to form sigma and pi bonds. Use the molecular orbital theory to determine bond order. Discover how bond order affects bond strength and bond energy.
14. Metallic Bonding: The Electron-Sea Model & Why Metals Are Good Electrical Conductors
Learn why metallic bonding is called the electron sea model. Discover why metals bond the way they do and why they are shiny, malleable and conduct electricity well.
