Conservation of Atoms
In this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The mass...

Mass Spectrometry
In this video Paul Andersen explains how a spectrometer was used to identify the presence of isotopes. This modified Dalton's original atomic theory because atoms of the same element had different masses. The functional parts of a mass...

TED-ED: The 2,400-year search for the atom - Theresa Doud
How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud...

The History of Atomic Chemistry: Crash Course Chemistry
How did we get here? Well, in terms of Atomic Chemistry, Hank takes us on a tour of the folks that were part of the long chain of other folks who helped us get to these deeper understandings of the world. From Leucippus to Heisenberg to...

Atomic Models
In this video Paul Andersen explains how the atomic model has changed over time. A model is simply a theoretical construct of phenomenon and so when we receive new data we may have to refine our model. Ionization energy data resulted in...

Elements and Molecules
In this video Paul Andersen explains how elements and molecules are made of atoms. In a pure sample of a pure substance the average mass remains the same. If more than one atom is found in a molecule the ration of average masses remains...

Dalton's Vision: The Birth of Atomic Theory
In 1803, John Dalton formulated his renowned theory of atoms. The principal tenets of his theory were as follows: ₷ Atoms were thought to be the smallest, hardest, densest, and indivisible particles of matter. Every element is made up of...
