Writing Lewis Structures Many Lewis structures can be drawn by inspection but a system helps to draw the more complex ones. One approach is too : 1. Draw a skeleton of the major (non-hydrogen) atoms with single bonds ( lines) between each one. Several general considerations will help produce a valid skeletal diagram. normal covalency number or number of bonds that each atom forms. Consider the For the major atoms these are: Element Bond(s) HYDROGEN 1 BORON 3 ALUMINUM 3 CARBON | 4 NITROGEN 3 OXYGEN 2 HALOGENS 1 Also note that hydrogen, boron, aluminum and the halogens seldom form multiple bond.

7.30 The bond in HF is said to be polar, with the hydrogen carrying a partial positive charge. For this to be true, the hydrogen atom must have less than one electron around it. Yet the Lewis dot structure of HF attributes two electrons to hydrogen. Draw a picture of the electron density distribution for HF and use it to describe how the hydrogen atom can carry a partial positive charge. How can these two models of the HF bond (the electron density and the Lewis structure) seem so different and yet describe the same thing?
