Ch 28: Properties & States of Matter

About This Chapter

Check out these engaging science lessons and quizzes to brush up on the properties and states of matter. You can access this chapter whenever you need to improve your understanding of these concepts for an exam, homework assignment or class project.

Properties & States of Matter - Chapter Summary

This convenient online science chapter helps you review the properties and states of matter. Taught by expert instructors, these simple lessons outline matter states, cell parts, ions, isotopes, molecular compounds and the periodic table. By the end of the chapter, you'll be equipped to:

  • Identify the states of matter
  • Assess the differences between protons and neutrons
  • Explain the function of the nucleus
  • Use ion formulas
  • Interpret the periodic table
  • Recognize different types of isotopes
  • Name and write binary molecular compound formulas

When you're finished with each lesson, try the accompanying self-assessment quiz to check your understanding of key terms and concepts. Our instructors are available to answer any questions you may have, and the chapter is accessible at any time that fits your schedule. You can also access the chapter's resources on any device that has an Internet connection.

8 Lessons in Chapter 28: Properties & States of Matter
States of Matter: Solids, Liquids, Gases, & Plasma

1. States of Matter: Solids, Liquids, Gases, & Plasma

Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.

Protons: Definition, Charge & Mass

2. Protons: Definition, Charge & Mass

Protons can be found in the nucleus of every atom. While originally it had been thought that protons were a fundamental particle, recent research has shown that protons are made of quarks. This lesson will cover the properties of the proton.

Neutrons: Definition & Concept

3. Neutrons: Definition & Concept

Neutrons are the big guys of the atom. This lesson explains the structure of the neutron, its properties, and some of its influences on the function of the atom.

Nucleus: Definition & Function

4. Nucleus: Definition & Function

A nucleus is like the brain of your cells. In this lesson, you will learn about its various responsibilities, and then you can test how well you grasp this material by taking a quiz.

Ions: Predicting Formation, Charge, and Formulas of Ions

5. 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.

The Periodic Table: Properties of Groups and Periods

6. The Periodic Table: Properties of Groups and Periods

How is the periodic table like the map you used on your last road trip? In this lesson, you will be introduced to the periodic table, the road map of chemists. We will discuss how the elements are organized and how you can use this organization to identify some of their major physical properties.

What Are Isotopes? - Definition, Types & Examples

7. What Are Isotopes? - Definition, Types & Examples

Not all atoms of an element are identical - atoms of the same element can have different numbers of neutrons. These different versions of the same element are called isotopes. In this lesson, we will discuss the examples and types of isotopes.

Naming & Writing Formulas for Binary Molecular Compounds

8. Naming & Writing Formulas for Binary Molecular Compounds

In this lesson, you will learn what it means to be a binary molecular compound and how to properly name these types of chemicals. You'll practice naming compounds, learn how to write formulas and finish by testing yourself with a short quiz.
