Use the ball and stick model kit to create the molecules below. Please note, the black ball will always be the central atom. Use the purple connectors to show lone pairs on the central atom. Then, draw a ball and stick model to show the 3-D structure for each molecule. Only draw the lone pairs on the central atoms unless it is an AX model.

Likewise in an organic chemistry class, activities involving ball‐and‐stick physical models in conjunction with computer‐generated 3D models yielded higher student scores on a post‐test than two‐dimensional (2D) textbook representations, or either the ball‐and‐stick or computer models alone 33.
The modular polypeptide molecular models described here have numerous advantages over existing ball-and-stick model kits that are currently used for in many science courses. Existing models that are completely rigid cannot be easily used to represent dynamic processes such as protein folding.
A molecular model, in this article, is a physical model that represents molecules and their processes. The creation of mathematical models of molecular properties and behaviour is molecular modelling, and their graphical depiction is molecular graphics, but these topics are closely linked and each uses techniques from the others.

This invention concerns the modeling of proteins and more specifically relates to an improved "ball-and-stick" modeling system. The protein model is a physical representation of a real molecule in biology and may consist of all-atom representation or a group representation of the constituent amino acids forming that molecule. The value of protein models is well understood in the field of ...
