About This Chapter
The Atomic Model, Energy & Matter- Chapter Summary
This chapter will help you identify information on important chemistry topics such as elements and the definition of an ion. You will be provided with the differences in elements, how an ion is formed, and the types of isotope, as well as a definition of atoms and how they make up elements. By the end of the chapter, you will have also covered the following topics:
- Information about elements and the ways they are described as building blocks
- Types of mixtures that elements make
- The four states of matter
- The importance of the atomic nucleus
- How electrons determine chemical reactivity
- Examples of radioactive substances
- Unique abilities of radioactive isotopes
All of the chapter topics are broken down into easily understandable parts of information, so you can quickly retain this material. A lot of these topics can be difficult to grasp but with the help of our professional and knowledgeable instructors, they can help you master it all. If you find yourself struggling through the lessons, you can ask our instructors for assistance. They will happily answer any questions you have.
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. Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry
What can the sun do that we can't? How do carbon atoms 'date'? Are radioactive isotopes helpful in the medical field? The answers to these questions can be found in this lesson on the applications of nuclear chemistry.
