The correct response is:
A 3D model shows how the different atoms are arranged, but the formula model does not.
A formula model provides the chemical formula of glucose (C₆H₁₂O₆), indicating the types and numbers of atoms involved, but it does not convey the spatial arrangement of those atoms. A 3D model, on the other hand, illustrates how the atoms are positioned in three-dimensional space, which is important for understanding the molecule's shape and potential interactions.
