Ch 28: CEOE Middle Level Science: The Atom & Atomic Theory

About This Chapter

Atoms and atomic theory are the focus of this chapter. Study these topics before you take the CEOE Middle Level Science exam. Entertaining video lessons and self-assessment quizzes will help you review and test your knowledge.

CEOE Middle Level Science: The Atom & Atomic Theory - Chapter Summary

Use this chapter to learn more about the atom and atomic theory. Gain the knowledge of an expert as you prepare to take the CEOE Middle Level Science exam for a teaching certification. When you reach the end of the chapter's video lessons, you might have a greater understanding of:

  • The composition of atoms and electron shells
  • Early atomic theory and average atomic mass
  • Electron configurations and the four quantum numbers
  • The Bohr model
  • Electron configuration at the ground state

As you watch the video lessons, you can pause them while you take in the information that's being presented. Written transcripts, self-assessment quizzes and a practice examination can help you get ready for the CEOE Middle Level Science exam's questions on atomic theory and the atom.

8 Lessons in Chapter 28: CEOE Middle Level Science: The Atom & Atomic Theory
Test your knowledge with a 30-question chapter practice test
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 Electron Shell

2. 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?

Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

3. 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.

Isotopes and Average Atomic Mass

4. 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

5. 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.

Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

6. Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

Each electron inside of an atom has its own 'address' that consists of four quantum numbers that communicate a great deal of information about that electron. In this lesson, we will be defining each quantum number and explaining how to write a set of quantum numbers for a specific electron.

The Bohr Model and Atomic Spectra

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.

Ground State Electron Configuration: Definition & Example

8. Ground State Electron Configuration: Definition & Example

The atom's electron structure is very important because it tells us about an atom's reactivity, and physical properties as well. In this lesson, we will cover the ground state electron configuration, which determines the electron's structure.
