Carbon

by Sandy Gade

This video (12:33) is the first in the Crash Course Biology series.  "And thus begins the most revolutionary biology course in history. Come and learn about covalent, ionic, and hydrogen bonds. What about electron orbitals, the octet rule, and what does it all have to do with a mad man named Gilbert Lewis?"Re-watch the whole video = 00:00Carbon is a Tramp = 01:51Electron Shells = 04:23The Octet Rule = 06:52Gilbert Lewis = 05:09Covalent Bonds = 04:41Polar & Non-Polar Covalent Bonds = 07:58Ionic Bonds = 08:29Hydrogen Bonds = 10:11
