Chapter 6 - Viewing Chemical Samples Changing the appearance of atoms Atoms can be represented by a variety of symbols that depict different kinds of information, such as spheres and space-filling spheres, or as combinations of symbols and spheres. NOTE The display style you choose to represent your chemical sample has no impact on its structure, or on any experiments you run using that chemical sample. CAChe allows you to change the following aspects of an atom’s appearance: • • • • atom labeling atom shape atom color the electrons of an atom. Changing atom labeling Choose from the following selection of atom labels: • • • • atomic symbol - displays the atom symbol; e.g., C for carbon • atom number - displays the CAChe atom number. hybridization - displays the atom hybridization; e.g., sp3 charge - displays the atomic charge; e.g., +1 partial charge - displays the calculated partial charge (as long as you have run a partial charge experiment on your chemical sample first) CAChe assigns a unique number to each atom, and numbering is in the same order that you added the atoms to the workspace. 6-8 CAChe for Windows User Guide
