The correct response is:
A 3D model shows how the different atoms are arranged, but the formula model does not.
A formula model typically provides information about the types and quantities of atoms in a molecule, such as the molecular formula (for glucose, C₆H₁₂O₆), but does not convey the spatial arrangement of those atoms. In contrast, a 3D model visually represents the three-dimensional arrangement of atoms and how they connect to form the structure of the molecule.
