Ch 24: TASC Science: Structure & Properties of Matter

About This Chapter

Get prepared for the TASC Science test with this chapter on the structure and properties of matter. Transition metals and main group elements are just a few of the many topics you'll find featured in these text and video lessons.

TASC Science: Structure & Properties of Matter - Chapter Summary

This chapter will give you a clearer understanding of the periodic table and properties of its groups and periods to help ensure you're comfortable with related questions on the TASC Science test. These lessons help you prepare for questions on:

  • The atom and the three main subatomic particles
  • Properties of groups on the periodic table
  • Valence electrons and the energy level of various elements
  • Atomic and ionic radii
  • Ionization energy
  • Electronegativity
  • Diagonal relationships
  • Transition metals and main group elements
  • Strong force
  • London dispersion forces

Our professional instructors use the fun videos to break these topics down and make them easy to comprehend. Take the practice quizzes after you feel like you have a good grip on the material to get an instant assessment of your understanding.

Objectives of the TASC Science: Structure & Properties of Matter Chapter

A passing score of 500 on the TASC Science exam indicates that your content knowledge is consistent with high school equivalency standards for the subject area. The physical sciences content domain on the exam is 36% of the test and is where you'll encounter questions on matter. The TASC Science test requires not just comprehension but also application, analysis and evaluation. The questions on the exam are mostly multiple-choice, just like the practice questions found in this chapter, though there are also technology-enhanced and constructed-response questions.

The Atom

1. The Atom

Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?

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.

Valence Electrons and Energy Levels of Atoms of Elements

3. 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

4. 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

5. 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

6. 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

7. 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

8. 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!

London Dispersion Forces (Van Der Waals Forces): Weak Intermolecular Forces

9. London Dispersion Forces (Van Der Waals Forces): Weak Intermolecular Forces

Learn how London dispersion forces are created and what effect they have on properties such as boiling and melting points. Discover this weak intermolecular force and how it is one of the Van der Waals forces.
