Molecular Models

Atoms are the building blocks of matter, and they combine to make molecules. Molecules are so small that it is nearly impossible to take a picture of them, even with very powerful microscopes. But scientists know how to make models of molecules, and the models help scientists study how molecules interact.

Molecules can be represented by simple spheres (atoms) joined by cylinders (atomic bonds). This type of model can represent a simple molecule, like water, or a very complex molecule, such as DNA.



Why is it called a mirror image? What so mirror molecules look like?
