# Chemical bonding

##### Three brief tutorials for General Chemistry

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. One of the most fundamental but little-taught of these is the electron tunneling model. Students: learn about this and teach your teacher!

Polar covalence - partial ionic character, electronegativity, and the fictional "ionic" bond. Discover three- and four-dimensional bond-type spaces.
