Question

there are several different models that represent compounds. one type of model is shown. what type of model is shown? a structural formula a chemical formula a space - filling model a ball - and - stick model

Explanation:

A ball - and - stick model uses spheres (balls) to represent atoms and sticks to represent the bonds between them. In the given image, spheres are used for atoms and sticks for bonds. A structural formula is a two - dimensional representation showing the arrangement of atoms and bonds in a molecule. A chemical formula just shows the types and numbers of atoms in a compound. A space - filling model shows atoms as spheres with volumes based on their van der Waals radii and does not have distinct sticks for bonds.

Answer:

a ball - and - stick model
