About This Chapter
Radioactivity - Chapter Summary and Learning Objectives
This chapter is designed to provide you with an overview of nuclear chemistry and processes, or what happens when atomic nuclei collide. The instructor will introduce you to radioactive isotopes, a unique class of atoms with unstable nuclei that we are exposed to everyday. You'll also become familiar with the real-world applications of nuclear chemistry and reactions.
Using easy-to-understand timelines and visuals, the instructor will explain nuclear equations and what happens to atomic particles when they emit radiation. You'll also learn about the natural and man-made sources of nuclear radiation, including their associated risk factors. When you have finished watching the videos and taking the self-assessment quizzes, you should be able to:
- Describe the interactions between unstable atomic nuclei.
- Discuss nuclear power and reactions, including fission, carbon dating and radiation therapy.
- Demonstrate your understanding of Einstein's famous equation.
- Define a radioactive isotope or nuclide and how much time it will take to decay or react.
- Identify the three main types of radiation and how they affect decaying atoms.
- Identify the three main types of radioactive decay, including alpha, beta and gamma decay.

1. 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.
2. 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.
3. Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy
When you hear the term 'nuclear power,' what comes to mind? Do you know where that energy and power is coming from? In this lesson, we are going to zoom in on the nucleus of a helium atom to explain how something as small as a nucleus can produce an extremely large amount of energy.
4. 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.
5. 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.
6. 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.
