In each of the generic models in the Molecular Geometry column below, lone pairs are simulated as white balls. The use of white for lone pairs allows the user to use the "Options> Display Hydrogens" menu option (right-click on a Windows computer, or click-hold on a Macintosh) to hide or show the lone pairs. In this column, in order to show the comparison among different shapes, a consistent color pattern is used throughout. In the "Example" molecules, no lone pairs are shown. Any white balls in the "Example" molecules are actual hydrogen atoms.
