Join award winning teachers Jonathan Bergmann and Aaron Sams as they interactively teach Chemistry: 2.6 Ionic Charge and Polyions. Ions are defined as atoms or groups of atoms with a charge. Common monoatomic ion charges are labeled on the Periodic Table of the Elements. Polyatomic Ions ( groups of atoms with a charge) are also explained. (08:30)

Hank bursts our ideal gas law bubble, er, balloon, and brings us back to reality, explaining how the constants in the gas law aren't all that constant; how the ideal gas law we've spent the past two weeks with has to be corrected for volume because atoms and molecules take up space and for pressure because they're attracted to each other; that Einstein was behind a lot more of what we know today than most people realize; and how a Dutch scientist named Johannes van der Waals figured out those correction factors in the late 19th century and earned a Nobel Prize for his efforts.

You've heard of kilohertz and megahertz, but when things get down to the size of atoms, wave frequency gets to some seriously high values. Video discusses the various types of waves and why there is a difference is what you hear and see. Video is of good quality and is appropriate for high school students. Run time 07:02.

Thanks to the wonders of physics, astronomers can map a timeline of the universe’s history. Today, Phil’s going to give you an overview of those first few minutes (yes, MINUTES) of the universe’s life. It started with a Big Bang, when the Universe was incredibly dense and hot. It expanded and cooled, going through multiple stages where different kinds of matter could form. It underwent a phenomenally rapid expansion called inflation, which smoothed out much of the lumpiness in the matter. Normal matter formed atoms between 3 and 20 minutes after the bang, and the lumps left over from inflation formed the galaxies and larger structures we see today. (12:35)

Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the different sorts of atoms in the universe, and it has a wealth of information to tell us if we can learn to read it.

All physical phenomena of nature are explained by four forces. Two nuclear forces -- strong and weak -- dwell within the atomic nucleus. The fundamental force of gravity granges across the universe at large. So does electricity, the fourth fundamental force, which binds the atoms of all matter.

Taken from the legendary Cosmos series, this video features Carl Sagan discussing atoms and the origins of our chemical elements. He explains how they are fused together in the interiors of stars. "Where do the natural occuring chemical elements come from? Perhaps a seperate creation for each element? But all the elements are made of the same elementary particles; the Universe all of it, everywhere, is 99.9 percent hydrogen and helium." This video comes from Carl Sagan's Cosmos episode 9, "The Lives of Stars." NOTE: the end of the video cuts off abruptly. (09:23)

In this video adapted from NOVA scienceNOW, explore the potential of carbon nanotubes, whose strength and unique properties make them useful for a variety of applications. See animations of how carbon atoms bond to one another in different ways to make diamond, graphite, buckyballs, and nanotubes, and observe one method that is being researched to form and assemble carbon nanotubes into a long ribbon. Consider how a seemingly impossible application, such as an elevator from the surface of Earth to space, is now theoretically possible given this revolutionary new building material. (04:28)

This twelve-minute video explains how the decay of atoms changes the total number of protons and it also changes the atomic number of that element. All atoms or isotopes in elements have the equal probability of decaying. Decaying adds to the number of protons and decaying could be portrayed in a chemical equation. (12:30)

This interactive activity from ChemThink discusses ionic bonding—a type of chemical bond formed between two ions with opposite charges. Investigate how the transfer of electrons between atoms creates ions and how the mutual attraction of these charged particles forms ionic bonds. Also learn about trends in the periodic table of elements, and explore how the structure of an ionic compound relates to its formula.

There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. Yet, despite decades of effort, no one knows what this "dark matter" really is. Many scientists think it's likely that the mystery will be solved with the discovery of new kinds of subatomic particles, types necessarily different from those composing atoms of the ordinary matter all around us. The search to detect and identify these particles is underway in experiments both around the globe and above it. (03:12)

Today's Crash Course Chemistry takes a historical perspective on the creation of the science, which didn't really exist until a super-smart, super-wealthy Frenchman put the puzzle pieces together - Hank tells the story of how we went from alchemists to chemists, who understood the law of conservation of mass as proposed by a decapitated aristocrat, and explains how we came to have a greater understanding of how chemical compounds work and eventually a complete understanding of what atoms and molecules are.
