Ch 15: ORELA General Science: The Periodic Table

About This Chapter

Master the periodic table with our video lessons and quizzes. These lessons help you prepare to answer related questions on the ORELA General Science exam.

ORELA General Science: The Periodic Table - Chapter Summary

When you need to review the periodic table's groups and periods for the ORELA General Science exam, use our fast videos to refresh your knowledge. The videos cover all the critical periodic table concepts you'll need to know for the exam, including:

  • Properties of groups and periods
  • Energy levels and valence electrons
  • Atomic and ionic radii
  • Ionization energy and electronegativity
  • Boiling point and metallic character
  • Transition metals and main group elements

These videos feature dynamic graphics and illustrations to make your preparation for the exam fun and easy. You'll also find transcripts and quizzes to help you review key definitions and major concepts covered in each lesson.

Objectives of the ORELA General Science: The Periodic Table Chapter

The ORELA General Science exam is a required part of the teacher licensing process for prospective science teachers in Oregon. It is made up of multiple-choice questions covering four content domains. The periodic table is a concept tested in the physical science domain, which has 37% of the exam's questions. The format of the questions you'll see on the exam is mirrored in our quizzes, so you can get comfortable with the question style before you register.

7 Lessons in Chapter 15: ORELA General Science: The Periodic Table
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.

Valence Electrons and Energy Levels of Atoms of Elements

2. 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

3. 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

4. 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

5. 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

6. 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

7. 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!
