What is a Chemical Formula? - Definition, Types & Examples

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.

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.

Ions: Predicting Formation, Charge, and Formulas of Ions

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.

Ionic Compounds: Formation, Lattice Energy and Properties

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.

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

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.

Writing Ionic Compound Formulas: Binary & Polyatomic Compounds

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.

Covalent Compounds: Properties, Naming & Formation

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.

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.

Lewis Dot Structures: Resonance

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.
