About This Chapter

Enjoy this comprehensive overview of the periodic table, designed to enhance your preparations for the CEOE Middle Level Science assessment. You can improve your ability to succeed on the exam by reviewing video lessons and taking short quizzes.

CEOE Middle Level Science: The Periodic Table - Chapter Summary

The lessons in this chapter are filled with information you can use to answer questions related to the periodic table on the CEOE assessment. Upon completion of this chapter, you will be able to:

  • Identify and describe the properties of groups and periods associated with the periodic table
  • Describe valence electrons and energy levels of atoms and elements
  • Share details about atomic and ionic radii
  • Define and describe ionization energy
  • Provide the meaning of electronegativity
  • Explain the diagonal relationship, metallic character and boiling point
  • Differentiate between and describe the properties of transitional metals and main group elements

After choosing the first lesson to watch, you can easily navigate the lessons by scrolling through the right-hand sidebar and selecting any you'd like to view in the sequence you'd prefer. Enjoy the convenience of learning more about the periodic table from the comfort of your home, or on the go via your smartphone or tablet.

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!
