Ch 19: ILTS Biology: The Periodic Table of Elements

About This Chapter

Use these lessons to re-familiarize yourself with the periodic table of elements, ionization energy, electronegativity and other related topics as you study for the ILTS Biology exam. Our lively videos and self-assessment quizzes can help you get ready for these types of exam questions.

ILTS Biology: The Periodic Table of Elements - Chapter Summary

This chapter's lessons can aid in your review of the elements and the periodic table while you get ready for the ILTS Biology exam. Our videos cover the following concepts:

  • Definition of elements
  • How the periodic table is arranged
  • Electron clouds and shells
  • Valence electrons
  • Atomic and ionic radii
  • Ionization energy and electronegativity
  • The diagonal relationship,
  • Metallic character and the boiling point
  • Differences in transitional metals and main group elements

You can review these lessons whenever you have a few minutes. Access them with a desktop computer, cell phone or tablet. Each lesson is followed by a short quiz that lets you assess your progress. If you need extra review, a clickable timeline makes it easy to hop back to a specific spot in the lesson.

ILTS Biology: The Periodic Table of Elements Chapter Objectives

The ILTS Biology exam assesses your knowledge of biology fundamentals, and passing it is one of Illinois' requirements for a teaching certification in the subject. The exam consists of six subareas, and questions on the material in this chapter are in the physical science subarea of the test.

All questions on the ILTS Biology test are multiple-choice, like the questions on our lesson quizzes. Taking these quizzes will give you an idea of what you'll encounter on exam day, in addition to letting you evaluate your learning.

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.

The Periodic Table: Properties of Groups and Periods

2. 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

3. 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

4. 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

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.

The Diagonal Relationship, Metallic Character, and Boiling Point

8. 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

9. 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!
