Ch 4: Chapter 4: Atoms - Holt Physical Science With Earth & Space Science

About This Chapter

The Atoms chapter of this Holt Science Spectrum - Physical Science with Earth and Space Science Companion Course helps students learn the essential lessons associated with atoms. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Atoms textbook chapter.

How It Works:

  • Identify the lessons in the Holt Atoms chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the topics on atoms you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Contributors to early atomic theory
  • The major components of an atom
  • What atomic and mass numbers represent
  • How grams are converted to moles
  • What valence electrons are
  • How electron transitions can happen
  • The Bohr model

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.

What is An Atom? - Definition & Examples

2. What is An Atom? - Definition & Examples

After watching this video, you will be able to explain what an atom is, how it is structured, what they are made from, and give some examples of elements. A short quiz will follow.

Atomic Number and Mass Number

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.

How to Convert Grams to Moles

4. How to Convert Grams to Moles

The mole is a standard unit in chemistry and is a way to measure the amount of a substance. In this lesson, we will learn how to convert the amount of a substance that is measured in grams to moles.

The Bohr Model and Atomic Spectra

5. 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.

Valence Electrons and Energy Levels of Atoms of Elements

6. 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.

Electron Transitions & Spectral Lines

7. Electron Transitions & Spectral Lines

This lesson discusses how electrons transition between energy levels, why they do this, how photons are involved, how absorption and emission spectra come into play, and what the Lyman, Balmer, and Paschen series are.
