About This Chapter

Check out the succinct, engaging video lessons in this chapter on the periodic table to get yourself ready for the Praxis Middle School Science exam. Each lesson is followed by a short quiz you can use for self-assessment to be sure you're ready for test day.

Praxis Middle School Science: Periodic Table - Chapter Summary

Are you ready to teach middle schoolers about science? Use our instructor-guided video lessons about the periodic table, created with you in mind, so you can successfully complete the Praxis Middle School Science test and prove you're ready to teach the subject. Lesson content includes:

  • The nature and characteristics of elements and electron shells
  • Properties of groups and periods on the periodic table
  • Review of valence electrons and atomic energy levels of elements
  • Trends of radii, ionization energy, electronegativity, metallic character and boiling point across the periodic table
  • Diagonal relationships of elements on the table
  • Differences between transition metals and main group elements

Taking the self-assessment quizzes following each chapter will give you confidence in your comprehension and retention of the subject matter. The video lessons are short enough and easy to navigate, so you can watch them anytime, anywhere - even from your mobile device.

Praxis Middle School Science: Periodic Table Chapter Objectives

Most states require you to successfully complete the Praxis Middle School Science test to prove you're ready to teach science to middle school students. The topics covered in this test prep guide about the periodic table purposely correspond to chemistry objectives listed as fair game on the physical sciences section of the exam, which constitutes about 22% of the exam (and includes other sciences besides chemistry).

Subjects pertaining to the periodic table that could be tested in the physical sciences section of the test include the organization of the periodic table in terms of groups, periods and characteristics of elements (such as symbol, atomic number, atomic mass, etc), as well as trends in chemical reactivity and its relationship to position on the table. The Praxis is a computer-based test with 125 total questions.

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.

What Are Isotopes? - Definition, Types & Examples

2. 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.

The Periodic Table: Properties of Groups and Periods

3. 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.

The Electron Shell

4. The Electron Shell

You may be familiar with the role of electrons in electrical devices, but did you know that electrons also determine the chemical reactivity of everything around you?

Valence Electrons and Energy Levels of Atoms of Elements

5. Valence Electrons and Energy Levels of Atoms of Elements

The periodic table contains a wealth of information. This lesson will explain how to use it to quickly determine the most useful information about the most important electrons. We will be focusing our discussion on valence electrons and energy levels.

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

6. 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

7. 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

8. 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.

The Diagonal Relationship, Metallic Character, and Boiling Point

9. The Diagonal Relationship, Metallic Character, and Boiling Point

What may have once seemed like a bunch of random squares with letters in them is now shaping up to be one very organized chemistry reference. In this lesson you will discover three other trends that are found on the periodic table: the diagonal relationship, trends in metallic character, and trends in boiling point.

Transition Metals vs. Main Group Elements: Properties and Differences

10. Transition Metals vs. Main Group Elements: Properties and Differences

Which is better: to be steadfast and consistent or to be a colorful chameleon? This lesson compares and contrasts the main group elements and the transition metals. Then make your own decision!
