Ch 27: TExES Physical Science 6-12: Radioactivity

About This Chapter

Discover what you know about radioactivity using our video lessons and quizzes. This type of review can help you prepare to answer specific questions you will encounter on the Texas Examinations of Educator Standards (TExES) Physical Science 6-12 exam.

TExES Physical Science 6-12: Radioactivity - Chapter Summary

What is radioactive decay? What are some aspects of nuclear power? What are the types of nuclear reactions? These are among the topics you can review when you access the lessons in this chapter. Once you have viewed these lessons and fully understand the concepts discussed, you should be prepared to answer relevant questions found on the TExES Physical Science 6-12 exam. The lessons can help you do the following:

  • Outline the types of radioactive decay and how each impacts the nucleus
  • Balance nuclear equations and predict the product of a nuclear reaction
  • Calculate radioactive decay and interpret decay graphs
  • Explain the applications of nuclear decay, including fission, carbon dating and imaging
  • Define nuclear reaction and give examples
  • Detail the uses for radioactive substances
  • Identify the safety concerns associated with radioactive waste and nuclear power plants

Using detailed examples and illustrations, the lessons present the material in a concise and easy manner. Each lesson allows you to measure what you've learned with a self-assessment quiz that uses a multiple-choice format just as you will find on the actual TExES Physical Science 6-12 exam.

Types of Radioactive Decay and Their Effect on the Nucleus

1. Types of Radioactive Decay and Their Effect on the Nucleus

What is meant by the term 'radioactive'? In this lesson we will break down the three main types of nuclear decay particles and discuss their composition, their effect on the nucleus, and their applications.

Balancing Nuclear Equations & Predicting the Product of a Nuclear Reaction

2. Balancing Nuclear Equations & Predicting the Product of a Nuclear Reaction

When a radioactive particle gives off radiation, what happens to the particle? This lesson will explain the three major types of radiation and what effect they have on the decaying atom.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

3. Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

What causes a radioactive particle to decay? We'll never really know, but our best guess lies in probability. In this lesson, we are going to focus on the half-life, a way of measuring the probability that a particle will react.

Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

4. 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.

Nuclear Reaction: Definition & Examples

5. Nuclear Reaction: Definition & Examples

Learn the differences between a nuclear reaction and a chemical reaction. Also learn how the nuclear reaction involves subatomic particles including protons and neutrons. Discover the different types of nuclear reactions including fission and fusion and also how a nuclear power plant works to produce energy.

What Are Radioactive Substances? - Examples & Uses

6. 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.

Risks of Nuclear Power Plants and Radioactive Waste: Safety and Health Concerns

7. Risks of Nuclear Power Plants and Radioactive Waste: Safety and Health Concerns

Nuclear power can generate electricity without greenhouse gas emissions. However, there are concerns about its safety. Learn about the safety and health concerns associated with the threat of nuclear meltdowns, as well as the challenges involved in storing radioactive waste.
