Ch 18: Elements & The Periodic Table

About This Chapter

Learn about the different types of elements on the periodic table by watching the video lessons found in this chapter. These lessons can help you better understand how elements are grouped and their defining properties.

Elements & The Periodic Table - Chapter Summary

If you would like to have a better understanding of the field of chemistry, it's essential that you first make sure that you understand the different types of elements comprising all matter. You may know that these elements are grouped on something called the periodic table, but how much do you know about the way the table is organized and the characteristics of different types of elements it lists?

Find the answers to these questions by going through this chapter and watching each of the helpful online video lessons. These lessons go over essential topics on the types of elements and the basic chemical properties that define them. Included in this chapter are specific lessons on topics such as:

  • Properties of the groups and periods on the periodic table
  • Details on metals and nonmetals
  • List of noble gases
  • Atomic and ionic radii
  • Ionization energy and electronegativity related to groups on the periodic table

You can use the video tags to jump to the main points in each lesson without having to watching the video from the beginning. Once you feel confident in your knowledge of these topics, answer the questions found in the chapter's practice quizzes and final exam to see how much you have understood. If you would like more information on a specific point, the chapter also offers you the option of messaging the lesson instructors.

The Periodic Table: Properties of Groups and Periods

1. 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.

Metals on the Periodic Table: Definition & Reactivity

2. Metals on the Periodic Table: Definition & Reactivity

Look around for a second...how many metallic things can you see? Generally when we think of metals, we think of substances that are shiny and durable; however, they're also in our food and in our bodies. Learn what makes a metal a metal and why metals are special.

Nonmetal Elements on the Periodic Table: Definition, Properties, & Reactions

3. Nonmetal Elements on the Periodic Table: Definition, Properties, & Reactions

Nonmetal elements are omnipresent and essential for life. Learn about the properties and typical reactions of these important elements, and then assess your new knowledge with a quiz.

Noble Gases: Definition, List & Properties

4. Noble Gases: Definition, List & Properties

Elements are grouped on the periodic table based on their chemical properties. In this lesson, you will learn about a group of elements known as the noble gases and their unique properties.

Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

5. Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

Atoms are VERY tiny. How do we measure their size? This lesson will explain how the size of an atom is measured and teach you how to predict the relative size of an atom based on where it is located on the periodic table.

Ionization Energy: Trends Among Groups and Periods of the Periodic Table

6. Ionization Energy: Trends Among Groups and Periods of the Periodic Table

Do you know someone who has undergone radiation as a form of cancer treatment? Have you ever thought about why X-rays have health risks? Watch the video to find out what these types of radiation are really doing to atoms, define ionization energy and identify ionization trends on the periodic table.

Electronegativity: Trends Among Groups and Periods of the Periodic Table

7. Electronegativity: Trends Among Groups and Periods of the Periodic Table

How is fluorine like a child that doesn't share his or her toys? Find out in this video on electronegativity where we will discuss group and periodic trends among the elements.
