This edition: Making Molecules: Lewis Structures and Molecular Geometries
When molecules form, the elements bond to one other by sharing or exchanging electrons. The “Octet Rule” predicts how atoms will combine to fill the eight slots in their outer shells. The program shows how this simple, but powerful, bonding mechanism — when combined with electron pair repulsion — leads to the 3-dimensional structure of molecules. Using these principles, scientists can build molecules that disrupt the chemical processes of cancer cell replication. Lewis structures, atomic model configurations, VSEPR theory and radicals are discussed.
