Which best explains the difference between a ball-and-stick model of a chemical compound and a space-filling model?

Both ball-and-stick and space-filling models can represent molecules in three dimensions. Ball-and-stick models make the connections between atoms clear, but their balls do not accurately show the atoms’ relative sizes. Space-filling models show the relative sizes of atoms, while the bonds are not drawn as separate sticks.
