File extension BS description:
Ball-and-stick models and space-filling models (also known as Calotte models) are 3D or spatial molecular models which serve to display the structure of chemical products and substances or biomolecules. Conformational isomerism is the phenomenon of molecules with the same structural formula but different conformations (conformers) of atoms about a rotating bond. ... Cyclohexane is a cycloalkane with the molecular formula C6H12. ... This is a calotte model of cyclohexane. ... The space we live in is three-dimensional space. ... A molecular model, in this article, is a physical model that represents molecules and their processes. ... A chemical substance is any material substance used in or obtained by a process in chemistry: A chemical compound is a substance consisting of two or more chemical elements that are chemically combined in fixed proportions. ... Water and steam are two different forms of the same chemical substance A chemical substance is a material with a definite chemical composition. ... A representation of the 3D structure of myoglobin, showing coloured alpha helices. ...
With ball-and-stick models, the centers of the atoms are connected by straight lines which represent the covalent bonds. Double and triple bonds are often represented by springs, which form curved connections between the balls. The bond angles and bond lengths reflect the actual relationships, while the space occupied by the atoms is either not represented at all, or only denoted essentially by the relative sizes of the spheres.
