About This Chapter
ASVAB: Matter & Atomic Structure - Chapter Summary
This Matter and Atomic Structure chapter will ensure that you have a handle on the states of matter as well as the physical and chemical properties of matter. Additional questions that you'll be prepared for on the ASVAB after studying this chapter could involve:
- Atomic number
- Mass number
- Electron configurations
- The Bohr model
- Avogadro's number
- Transition metals and main group metals
Watch the videos on a computer or handheld device, and you'll improve your understanding and boost retention of the information. Once you've completed any lesson, you can take a practice quiz to get immediate feedback on your comprehension.
Objectives of the ASVAB: Matter & Atomic Structure Chapter
The ASVAB assesses your potential for the military based on your knowledge and skills indicated across the exam. Content that you become familiar with in the Matter & Atomic Structure chapter may come in handy for questions that are asked in the General Science subtest of the ASVAB. All of the test items included in the GS subtest have a multiple-choice structure.
1. Matter: Physical and Chemical Properties
How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.
2. States of Matter: Solids, Liquids, Gases, & Plasma
Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.
3. Atomic Number and Mass Number
Atoms are the basic building blocks of everything around you. In order to really understand how atoms combine to form molecules, it's necessary to be familiar with their structure. In this lesson, we'll dissect atoms so we can see just what really goes into those little building blocks of matter.
4. Electron Configurations in Atomic Energy Levels
This lesson will explain what the electrons are doing inside the atom. Tune in to find out how we specify where they are located and how this location description will help us predict an element's properties.
5. 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!
6. Isotopes and Average Atomic Mass
When you drink a glass of water, you are actually drinking a combination of heavy water and light water. What's the difference? Is it harmful? This video will explain the difference between the two types of water and go into detail on the significance of the different isotopes of elements.
7. The Bohr Model and Atomic Spectra
Do you ever wonder where light comes from or how it is produced? In this lesson, we are going to use our knowledge of the electron configurations and quantum numbers to see what goes on during the creation of light.
8. Avogadro's Number: Using the Mole to Count Atoms
How do we move from the atomic world to the regular world? Because atoms are so tiny, how can we count and measure them? And what do chemists celebrate at 6:02 AM on October 23rd each year? In this lesson, you will be learning how Avogadro's number and the mole can answer these questions.
