Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

1. Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

During a nuclear reaction, small amounts of mass are destroyed and converted into massive amounts of energy in a process called mass defect. Learn about nuclear binding energy, mass defect, and how energy and mass are directly related.

Nuclear Reaction: Definition & Examples

2. Nuclear Reaction: Definition & Examples

A nuclear reaction, such as fission and fusion, affects the nucleus of an atom and changes its particles in the process. Explore the differences between nuclear reactions and chemical reactions, the differences between nuclear fission and fusion, and how they are used for energy.

Types of Radioactive Decay and Their Effect on the Nucleus

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

Radiation is a byproduct of nuclear energy, but only 1% of all radiation comes from the nuclear industry. Most radiation comes from natural sources, such as rocks or the Sun. Learn about the sources of radiation, the three main types of radioactive decay (alpha, beta, & gamma), and the effect of nuclear decay on the nucleus.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

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

Scientists use the amount of time it takes for half of an isotope to react or decay, or half-life, of carbon-14 in carbon dating experiments to determine the age of substances. Learn about half-life, decay graphs, and how to calculate radioactive decay.

Principles of Radiometric Dating

5. Principles of Radiometric Dating

Radiometric dating is a process used to determine the age of the Earth's rocks and other geological materials, such as carbon. Learn about the principles of radiometric dating and understand its processes by studying radioactive decay, parent and daughter nuclides, and types of decay.

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

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

Despite being considered climate-friendly, nuclear power plants come with a number of risks. Learn how nuclear power works, the definition of a meltdown, and the health and safety concerns surrounding radioactive waste.

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

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

Nuclear chemistry is the science of using radioactive isotopes and other nuclear reactions to diagnose and treat medical conditions and also to determine the age of artifacts through a process called carbon dating. Learn about nuclear fusion, nuclear fission, tracers, imaging, and practical applications of nuclear chemistry.

Nuclear Chemistry: Nuclear Shell Model

8. Nuclear Chemistry: Nuclear Shell Model

Learn about the nuclear shell model and how it describes nuclear stability. Examine how different nucleon configurations create stable elements with examples.
