Atoms and the Periodic Table
After discovering plutonium, Glenn Seaborg was given the opportunity to determine its periodic symbol. Rather than going with the obvious Pl, he went with Pu as a joke. The designation was approved and is now on every periodic...
Crash Course
The Nucleus
Einstein didn't just discover relativity, he proved the existence of atoms in 1905 — more than 110 years ago. Discover how he did it and begin learning about basic chemistry: parts of an atom, atomic mass, atomic number, and how to read...
Crash Course
Stoichiometry: Chemistry for Massive Creatures
Moles exist in chemistry? These are not animals that live underground and dig through your gardens — they are quantities of elements. Learn about moles and how they help chemists determine amounts of substances (from atomic mass to grams).

Isotopes
Altering the subatomic nature of an atom affects its properties. The video illustrates the idea of an isotope using Carbon-12, Carbon-13, and Carbon-14 as examples.
Berkeley University of California
Isotopes
Review carbon-12 with the final video in a 15-part series. The video first shows how to use mass spectrum results to determine the molar mass of carbon. It then determines the number of protons, neutrons, and electrons in carbon-12.
