- Define ionic compounds and write ionic compound formulas
- Describe covalent compounds and their formation
- Detail VSEPR theory and molecule shapes
- Explain hydrogen bonding as well as dipole-dipole and ion-dipole forces
- Discuss London dispersion forces
- Predict molecular shape using orbital hybridization and valence bond theory
- Analyze electronegativity, electron affinity and the oxidation states of transition metals
You can quickly gauge your understanding of each lesson by taking an accompanying practice quiz. There are also lesson transcripts that you can check out while you're studying. Track your progress along the way with the Dashboard.
1. Overview of Chemical Bonds
Learn about the most common kinds of chemical bonds: ionic, covalent, polar covalent, and metallic. Discover how they form and why they hold together. Take a quiz and see how much knowledge you've held onto.
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.
3. Electronegativity: Definition & Trends
The attraction of electrons is different depending on the element. This degree of attraction is measured by the element's electronegativity. In this lesson, we will discuss electronegativity, its trends in the periodic table, and bonding.
4. What Are Ionic Compounds? - Definition, Examples & Reactions
Ionic compounds are a common, yet special type of chemical compound. In this video lesson, you will learn about their formation and structure and see examples of compounds formed by ions.
5. Writing Ionic Compound Formulas: Binary & Polyatomic Compounds
In this lesson, you will learn how to write the chemical formulas for both binary ionic compounds and polyatomic ionic compounds when you are given only the name of the compound. You will see that it is actually quite simple when you learn the steps described in this lesson.
6. 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.
7. Electron Affinity: Definition, Trends & Equation
When an electron is added to an atom, a change in energy occurs. This change in energy is what we call the electron affinity. In this lesson, we will discuss electron affinity and its general trend in the periodic table.
8. Oxidation States of Transition Metals
Transition metals can be a little confusing, but this lesson will simplify things by explaining why transition metals can have more than one oxidation state. It will also touch on other topics such as half equations and colored solutions.
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.
