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.
The advantage of the ball-and-stick model as opposed to the Calotte model is that it allows better insight into the molecule’s bond structure.
