Ch 4: Holt Physical Science Chapter 4: Elements, Compounds, and Mixtures

About This Chapter

The Elements, Compounds and Mixtures chapter of this Holt Physical Science Textbook Companion Course helps students learn essential physical science lessons on elements, compounds and mixtures. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Elements, Compounds and Mixtures textbook chapter.

How it works:

  • Identify the lessons in the Holt Physical Science Elements, Compounds and Mixtures chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the elements, compounds and mixtures topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Chemical and physical properties of elements
  • How compounds and molecules are built from elements
  • Combined elements and compounds create mixtures
  • Methods of separating mixtures, including chromatography, distillation and filtration
  • Solutions, solutes and solvents
  • The rate of dissolution
  • Solubility and solubility curves

What Are Elements?

1. What Are Elements?

An element is a unique type of matter which cannot be separated into parts that are different from the initial element. Learn how elements are represented through symbols, the particles (atoms) that make up elements, and how elements can combine to create different items in the real world.

Physical & Chemical Properties of Elements: Metals, Nonmetals & Metalloids

2. 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.

How Compounds and Molecules Are Built From Elements

3. How Compounds and Molecules Are Built From Elements

Compounds and molecules are built from elements composed of at least two atoms joined with a chemical bond. Learn how elemental personalities build compounds and molecules, explore ionic and covalent chemical bonds, and compare pure substances to mixtures.

Physical & Chemical Properties of Compounds: Types & Examples

4. 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.

How Compounds are Broken Down: Heat & Electricity

5. How Compounds are Broken Down: Heat & Electricity

Compounds can be broken down into smaller compounds or their basic elements by chemical change. Sometime this breakdown requires energy. Learn how some compounds are broken down with heat or electricity.

Creating Mixtures by Combining Elements & Compounds

6. 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.

Chromatography, Distillation and Filtration: Methods of Separating Mixtures

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

A mixture is defined as a physical combination of two or more substances that are not chemically combined. Learn about the types of mixtures and the methods for separating mixtures (chromatography, distillation, evaporation, crystallization, filtration, dissolving, magnetism, and manual separation).

Solutions, Solutes, and Solvents

8. Solutions, Solutes, and Solvents

Solutions are homogeneous mixtures of two or more substances in which the solvent does the dissolving, while the solute is the solvent substance being dissolved. Explore the definitions and usage of solutions, solutes, and solvents.

The Rate of Dissolution: Factors and Definition

9. The Rate of Dissolution: Factors and Definition

Dissolution occurs when the solute in a solvent forms a solution. Learn about the factors and rate of dissolution, explore how like dissolves like, and define key terms such as the greater surface area, miscible, and immiscible.

Solubility and Solubility Curves

10. Solubility and Solubility Curves

Solubility refers to a solute's ability to dissolve; a solubility curve is defined as the relationship between a solute's solubility and the temperature. Learn to use solubility curves to identify and understand the differences among saturated, unsaturated, and supersaturated solutions.

Comparing Solutions, Suspensions & Colloids: Properties & Examples

11. 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.
