Recently in class and in the book, we have been discussing lewis structures of atoms and molecules as well as an introduction to molecular geometry. In class, we have looked at several molecules and have tried to remake them using connectable lego-like atoms and bonds. In the chem talk, a review about how valence electrons are used in bonding is present. It also goes into more about the VSEPR theory. This has to do with the distance between the electrons when bonded to a molecule. Since electrons are negative, they repel each other equidistantly. Different shapes of molecules are formed because of the repulsion theory. This all seems like it is easy to understand, especially when we get a chance to make the molecules with 3-D figures.
