Professor Sylvia Ceyer explains the steps required to create a Lewis structure, using the cyanide ion and thionyl chloride as examples. She discusses formal charge within a molecule, skeletal structure of chain molecules, and resonance structures using the nitrate ion as an example.

This lecture brings experiment to bear on the previous theoretical discussion of bonding by focusing on hybridization of the central atom in three XH3 molecules. Because independent electron pairs must not overlap, hybridization can be related to molecular structure by a simple equation. The "Umbrella Vibration" and the associated rehybridization of the central atom is used to illustrate how a competition between strong bonds and stable at...more

In this lecture, Professor Diamond wraps up her discussion of the nervous system and moves on to the urinary system, beginning with the kidney. She concludes her discussion of the nervous system by describing the cochlea and diagramming its structure, and she indicates how cilia (hair cells) respond to and transmit information about vibrations in the fluid inside the cochlea. Professor Diamond then diagrams the constituents of the urinar...more

Nick Earl, General Manager of Electronic Arts Redwood Shores Studio, talks about how the General Manager's job is to run one of EA's six studios, which are the places where they actually build the product. The GM administers and manages the portfolio of products at the site. Each product is then run by an executive producer. The executive producers are entrepreneurs in their own right and the products are managed almost like independent v...more

In this lecture Professor Sylvia Ceyer covers the electron structure of multielectron atoms, beginning with simple electron configurations. The Aufbau Principle is explained, as well as the Pauli Exclusion Principle and Hund's Rule. Core electrons and valence electrons are discussed, concluding with electron configurations of ions and photoelectron spectroscopy.
