Strong Interaction: The Four Fundamental Forces of Physics #1b
There is a force stronger than electricity or gravity, so scientists named it the strong force. The video continues the explanation of the strong force and the way it works. It also describes the limitations, such as only working in very...

What is a Weighted Average?
Have you ever wondered why the atomic mass listed on the periodic table isn't a whole number? This video explains how weighted averages are calculated and relates the average to the relative atomic mass. Viewers are then given an element...

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...

Atomic Structure
The Rutheford plum pudding model of an atom, as well as the nuclear model, are the subject of a video that also includes an explanation of protons, neutrons, electrons, nucleus, atomic mass, atomic charge, and ions.
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...

Electron Configuration Example
What does an atom look like? The instructor in a tutorial video models how to use the periodic table to determine the number of subatomic particles. He then uses the number of electrons to create an orbital diagram. Finally, Groves...

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.

Structure of an Atom
Just because we can't see an atom doesn't mean we can't study it! The video examines the makeup of the atom. It explains the roles of the protons, neutrons, and electrons.

Atomic Structure
How are atoms structured? Viewers of the video first learn about atoms and atomic structure, including the nucleus and electron shells. The video then describes how atomic numbers and atomic masses are expressed on atomic symbols. You'll...
