Elements & Atoms

How elements relate to atoms. The basics of how protons, electrons and neutrons make up an atom.

The Nucleus: Crash Course Chemistry #1

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles—the proton, neutron and electron—come together in trillions of combinations to form . . . everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever—stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.
