- Space-filling model
Space-filling models (also known as calotte models or CPK models [Robert B. Corey and Linus Pauling (1953): Molecular Models of Amino Acids, Peptides, and Proteins. Review of Scientific Instruments, Volume 24, Issue 8, pp. 621-627. doi|10.1063/1.1770803] by Corey, Pauling and Koltun), like
ball-and-stick models, belong to the 3D or spatial molecular models, which serve to display the structure of chemicalproducts and substances or biomolecules.
The calotte model is a further development of the ball-and-stick model, with which the configuration of
molecules can be vividly presented. With it, the atoms of individual elements are represented by multicolored spherical sections. Atom size, bond angleand bond lengthcorrespond to the actual relationships. The surface usually represents the van der Waals radiusof the individual atoms..
