Ch 4: Properties of Elements, Compounds & Mixtures

About This Chapter

In this chapter, become acquainted with the properties of elements, compounds, and mixtures. Building confidence can actually help you do better on exams, and our lessons help you memorize terms, definitions, and formulas, which will expand your knowledge of chemistry and boost your confidence.

Properties of Elements, Compounds & Mixtures - Chapter Summary

Use this chapter to recall what you know about the properties of elements, compounds, and mixtures. The chapter has been divided into individual topics, making it easier to navigate the lessons and find the specific areas you need to review. While you can skip around, you can also watch the lessons in order, from the definition of elements all the way to an explanation of what makes liquids miscible.

As you go from one lesson to the next, you'll learn more about such topics as the building blocks of matter, chemically joined elements, the visibility of particles, and the role of solvents. By going through the entire chapter, you should be able to:

  • Describe elements
  • Identify how molecules and compounds are constructed from elements
  • Explain the chemical and physical properties of compounds
  • Show how to create solutions and mixtures by combining compounds of elements
  • Compare the properties of colloids, suspensions, and solutions
  • Point out three of the main methods for separating mixtures
  • Define the term solvent and provide examples
  • Establish the process of centrifugation
  • Offer examples of miscible liquids

All of our lesson materials have been designed by chemistry experts. These are individuals who possess advanced knowledge in the field of chemistry and who have devoted years of their life to studying this branch of science. Furthermore, our experts are experienced instructors, so they know how to use various approaches to reach learners of all levels.

What Are Elements?

1. What Are Elements?

Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.

How Compounds and Molecules Are Built From Elements

2. How Compounds and Molecules Are Built From Elements

Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.

Physical & Chemical Properties of Compounds: Types & Examples

3. 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.

Creating Mixtures by Combining Elements & Compounds

4. Creating Mixtures by Combining Elements & Compounds

Do you really know what's in your tap water? It's not just water - it's a mixture of many different things. In fact, most things are mixtures of different elements and compounds that are physically joined together.

Creating Solutions by Combining Elements & Compounds

5. Creating Solutions by Combining Elements & Compounds

When elements and compounds physically combine, we get mixtures. But sometimes we can't tell just by looking at something that it's a mixture because the components are so well mixed. When this happens, we have solutions.

Comparing Solutions, Suspensions & Colloids: Properties & Examples

6. Comparing Solutions, Suspensions & Colloids: Properties & Examples

With a few simple observations, you can classify a mixture as a solution, suspension or colloid. Learn how we use properties, such as visibility of particles, how light is affected and the ability of particles to settle out to classify mixtures.

Chromatography, Distillation and Filtration: Methods of Separating Mixtures

7. Chromatography, Distillation and Filtration: Methods of Separating Mixtures

What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.

What is Centrifugation? - Definition, Process & Uses

8. What is Centrifugation? - Definition, Process & Uses

Astronauts, hospitals, and you depend upon centrifugation all of the time! This lesson will explain how centrifugation works and then will discuss some uses of the centrifuge. Following your exploration of that information, you can test your knowledge with a quiz.

Miscible Liquids: Definition & Examples

9. Miscible Liquids: Definition & Examples

What is a miscible liquid? Learn what it means for a liquid to be miscible, and explore everyday liquids known to be miscible. Then test your understanding with a short quiz.
