About This Chapter
Simple Compounds & Chemical Formulas - Chapter Summary
Let us help you re-acquaint yourself with different chemical compounds and various chemical formulas. Our instructors will help you review methods for naming and writing compounds. They'll also walk you through the properties of Lewis structures. Specifically, you'll study:
- Types of chemical formulas
- The atomic octet rule
- Ionic formation, charge and formulas
- Properties, formation and lattice energy of ionic compounds
- Ionic and covalent compounds
- Types of Lewis structures
- Polyatomic ions and resonance in Lewis dot structures
Our instructors have specially developed the lessons in this chapter to keep you engaged in the learning process. Most of the lessons contain entertaining and informative videos to illustrate the material. You can take self-assessment quizzes along the way to test your knowledge. After completing all of the lessons, take the cumulative chapter exam to apply all that you have covered.
1. 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.
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. 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.
4. 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.
5. 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.
6. 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.
7. 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.
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.
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.
10. Lewis Dot Structures: Resonance
In this lesson, we'll review Lewis dot structures and how to draw them. Then, learn about resonance and resonance structures for molecules and polyatomic ions. Afterwards, assess your new knowledge with a quiz.
