John Denker The Mystery of Matter Search for the Elements This PBS video is an exciting three part series about one of the great adventures in the history of science the long and continuing quest to understand what the world is made of. Three hour long episodes tell the story of seven of historys most important scientists as they seek to identify, understand and organize the basic building blocks of matter. Hunting the Elements A Two. PBSNOVA video. Where do natures building blocks, called the elements, come from Theyre the hidden ingredients of everything in our world, from the carbon in our bodies to the metals in our smartphones. To unlock their secrets, David Pogue, technology columnist and lively host of NOVAs popular Making Stuff series, spins viewers through the world of weird, extreme chemistry the strongest acids, the deadliest poisons, the universes most abundant elements, and the rarest of the raresubstances cooked up in atom smashers that flicker into existence for only fractions of a second. Note this video is not viewable in Canada and possibly in other countries owing to stupid rights issues. Chemical Bonding. All about chemical bonding Steve Lower, SFU this 1. General Chemistry level. Includes separate sections on polar covalence, VESPR, hybrid orbitals, molecular orbitals, coordination complexes and metals. Chemical bonding the really basic stuff S. Lower, Simon Fraser U. Models of chemical bonding Do chemical bonds really exist Nobody has ever seen one, so the best we can do is construct models. Here is a brief summary of those you should know about. Covalent, ionic, or what Coming to terms with covalent, ionic, and metallic bonding, and with mixtures thereof. Guaranteed to give you more insight to this than your textbook doesThe electron tunneling model of chemical bonding How can those electron dot diagrams showing shared electrons happily sitting between the nuclei be consistent with the principle that opposite charges attract The model described here is the simplest one that really explains bonding, but you are unlikely to find it in any textbook VSEPR theory This summary with easy access to many images is a hypertext version of the chapter on this subject from a textbook by Mark Winnter U Sheffield. VSEPR for General Chemistry This Purdue University site features a useful set of practice problems and requires the downloadable CHIME plug in. Electrochemistry.
