About This Chapter
Atoms, Energy & Matter - Chapter Summary
This informative chapter clearly outlines energy, atoms and matter for your review. Our short lessons cover the atom and elements, plus the compounds and molecules that make up elements. Once you complete this chapter, you should be ready to:
- Provide an example of a mixture as it's used in chemistry
- Explain how an ion works and what it is
- Outline the different states of matter
- Detail the structure and size of an atomic nucleus
- Describe the different types of isotopes
- Define the electron shell and understand its function
- Discuss the uses of radioactive substances
- Identify some electrical, chemical and radioactive hazards as they apply to a science class environment
Move at your own pace as you review these topics, and feel free to re-watch any of the video lessons over again if you need to. We've made it easy to watch just one portion of a video with the video tabs feature provided in the Timeline. Then, take the short quiz provided with the video to ensure you've understood what you've learned. Our instructors are available to answer any questions you might have along the way.
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?
2. What Are Elements?
Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.
3. How Compounds and Molecules Are Built From Elements
Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.
4. Mixture in Chemistry: Definition & Examples
Very few of the chemicals and substances we encounter on a daily basis are in their pure form. Many of them are mixtures. In this lesson, you will learn about the types of mixtures recognized by scientists.
5. What Is an Ion?
Learn what an ion is and how it forms. We will look at some common ions and get to know the terms for the two types of ions. Take the quiz at the end to see how well you understand the lesson.
6. 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.
7. Atomic Nucleus: Definition, Structure & Size
The atomic nucleus is the central part of the atom. There is a lot to be told by the structure of the atomic nucleus. This lesson goes through the structure of the atomic nucleus and other factors that the atomic nucleus tells us.
8. What Are Isotopes? - Definition, Types & Examples
Not all atoms of an element are identical - atoms of the same element can have different numbers of neutrons. These different versions of the same element are called isotopes. In this lesson, we will discuss the examples and types of isotopes.
9. 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?
10. What Are Radioactive Substances? - Examples & Uses
This lesson will explain what a radioactive substance is, give examples of radioactive substances and describe how radioactivity is used in everyday life.
11. Chemical, Electrical & Radioactive Hazards in a Science Classroom
In this lesson you will learn about the types of hazards that can exist in science classrooms. Chemical, electrical, and radioactive hazards will be defined and discussed.
