Which Model Best Depicts a Molecule's Volume

Question

Which model best depicts a molecule's volume?
A)atomic
B)molecular
C)structural
D)ball-and-stick
E)space-filling

Accepted Answer

The space-filling model, also known as the CPK (Corey-Pauling-Koltun) model, best depicts a molecule's volume as it shows the relative size and position of atoms in a molecule as spheres. The spheres represent the atomic boundaries and the space between them depicts the actual volume of the molecule.
