Document Summary

The nobel prize in physiology or medicine 2004: richard axel & linda b. buck for the organization of the olfactory system. We often describe the shape of a molecule w/ terms that relate to geometric figures. These geometric figures have characteristic corners that indicate the positions of the surrounding atoms around a central atom in the center of the geometric figure. The geometric figures also have characteristic angles that we call bond angles. Lewis theory predicts there are regions of electrons in an atom. Some regions result from placing shared pairs of valence electrons b/w bonding nuclei (bonding pair) Other regions result from placing unshared valence electrons on a single nuclei (lone pair) Lewis theory says that these regions of electron groups should repel each other: because they are regions of negative charge. This idea can then be extended to predict the shapes of molecule.
