About This Chapter
Properties of Earth Materials - Chapter Summary
By going through these lessons on properties of earth materials, you can verify your understanding of how covalent and ionic compounds are formed. You can also gain a better understanding of why metals are shiny and malleable. After completing the chapter, you should feel confident and ready to:
- Discuss how elements have their own unique physical and chemical properties
- Provide examples of physical and chemical properties of compounds
- Identify decomposition and synthesis reactions
- Use bond energy to measure energy change of a chemical reaction
- Discuss ionic and covalent chemical bonds
- List the properties of a metallic bond
- Write ionic compound formulas
- Identify common elements that exist as molecules
Each lesson is accompanied by a brief quiz to assess how much of the content and details you can recall. Video timelines let you study all the lessons in sequential order or focus only on the topics you need to review. You can maximize the benefits of this resource by printing the quiz in worksheet form to use as a study guide.
1. Physical & Chemical Properties of Elements: Metals, Nonmetals & Metalloids
Elements are elementary! They are simple substances that cannot be broken down. Learn how each element has its own unique set of physical and chemical properties, and how we use those properties to categorize them as metals, nonmetals, and metalloids.
2. Physical & Chemical Properties of Compounds: Types & Examples
Compounds are made up of elements that are chemically joined. Like elements, compounds have properties that allow us to identify them. Learn about physical properties, like color, odor, melting point and boiling point, as well as chemical properties in this lesson.
3. States of Matter and Chemical Versus Physical Changes to Matter
The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.
4. Decomposition and Synthesis Reactions
Learn how to write, identify and predict the products of simple synthesis and decomposition reactions. This includes the composition of reactions with oxygen, of two metals, and of metals with nonmetals, as well as the decomposition of metal carbonates, metal chlorates and metal hydroxides.
5. Bond Energy: Definition & Equation
Chemical reactions involve the breaking and forming of chemical bonds. In this video lesson, we will learn about bond energy and how we can use it to measure the overall energy change of a chemical reaction.
6. Chemical Bonds: Ionic vs. Covalent
Atoms make up everything on Earth, and chemical bonds are what hold those atoms together. In this lesson, we'll discuss two very important types of chemical bonds: covalent and ionic.
7. What is a Metallic Bond? - Definition, Properties & Examples
The metallic bond is a type of chemical bond that occurs between atoms of metallic elements. It gives metals their unique properties that we don't see in nonmetal substances, as you'll learn in this lesson.
8. 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.
9. 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.
10. 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.
11. 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.
12. Common Elements that Exist as Molecules & Covalent Lattices
In this lesson you will learn about elements that exist as molecules and covalent lattices. You will also learn about the properties of some of these elements.
