TExES Physical Science 6-12: Atomic Structure - Chapter Summary

It's easy to get ready for the TExES Physical Science 6-12 test when you have help from this chapter on atomic structure. You'll watch short videos on early atomic theories and the scientists who discovered them. After completing this chapter, you should be ready to:

  • Discuss the scientific contributions of Thomson, Millikan, Rutherford and Dalton
  • Outline atomic spectra and the Bohr model
  • Define the atom
  • Explain mass number and atomic number
  • Share information about isotopes and average atomic mass
  • Identify electron configurations in atomic energy levels
  • Use the mole to count atoms

We've taken the stress out of your test preparations with this easy-to-understand chapter. Study as few or as many of the lessons as you like on your smartphone, tablet or computer to create a completely customizable study experience. Assistance from an expert is available in the Dashboard if you have any questions.

Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

1. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

Imagine firing a bullet at a piece of tissue paper and having it bounce back at you! You would probably be just as surprised as Rutherford when he discovered the nucleus. In this lesson, we are going to travel back in time and discuss some of the major discoveries in the history of the atom.

The Bohr Model and Atomic Spectra

2. 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.

The Atom

3. 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?

Atomic Number and Mass Number

4. 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.

Isotopes and Average Atomic Mass

5. 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.

Electron Configurations in Atomic Energy Levels

6. 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.

Avogadro's Number: Using the Mole to Count Atoms

7. 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.
