In chemistry, a formula indicates the type and number of atoms in the molecule. On the other hand, a three-dimensional (3D) model is a graphic representation that shows how atoms are arranged in the molecule.
- A 3D model shows how the different atoms are arranged, but the formula model does not (Option A).
- In a chemical formula, each element of the molecule is represented by its chemical symbol, and the number of atoms is indicated by a subscript.
- In this case, the formula of the glucose molecule is C₆H₁₂O₆
- A 3D molecular model shows the shape of the molecule in specific conditions such as, for example, physiological conditions (pH 7.2).
- The 3D molecular models are influenced by the spatial orientation of covalent bonds between atoms.
In conclusion, a 3D model shows how the different atoms are arranged, but the formula model does not (Option A).
