Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

1. 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.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

2. 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

3. 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

4. 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

5. 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.

Using Radioisotopes in the Sciences

6. Using Radioisotopes in the Sciences

How are radioisotopes used in science? Learn about their applications for the dating of rocks, in medicine, environmental science and materials science. See what you know with a quiz.

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.
