We explore the nature of radioactivity and describe the types of radioactive decay that occur.
We travel to a nuclear power plant to explain what happens inside an atom that undergoes fission and we show you how that process is harnessed to create electricity.
We explore how and why fusion occurs between atoms, what products result from this type of reaction, and how stars use this process to create energy and the atoms of which we are made.
We explain half-life qualitatively, mathematically, and graphically. We also look at how we use this principle to find the age of objects.
