Ch 11: Holt Physical Science Chapter 11: Introduction to Atoms

About This Chapter

The Introduction to Atoms chapter of this Holt Physical Science Textbook Companion Course helps students learn essential physical science lessons on atoms. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Introduction to Atoms textbook chapter.

How it works:

  • Identify the lessons in the Holt Physical Science Introduction to Atoms chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the introductory atoms topics 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:

  • Early atomic theory
  • The Bohr model and atomic spectra
  • The atom
  • Isotopes and average atomic mass
  • Atomic number and mass number

6 Lessons in Chapter 11: Holt Physical Science Chapter 11: Introduction to Atoms
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.

Modern Atomic Theory: Electron Clouds, Schrodinger & Heisenberg

3. Modern Atomic Theory: Electron Clouds, Schrodinger & Heisenberg

Does an atom look more like a solar system or a cloud? Learn how the early atomic theory has evolved into the modern atomic theory and changed the way science views the atom. Learn about contributions from Schrodinger and Heisenberg.

The Atom

4. 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?

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.

Atomic Number and Mass Number

6. 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.
