Final answer:
The space-filling model is ideal for illustrating the relative sizes of atoms in a molecule, while the wedge-and-dash representation provides a good three-dimensional sketch of its structure. Bond distances and angles offer specifics on spatial dimensions.
Step-by-step explanation:
To write down information about a molecule that gives an accurate picture of the relative sizes of the atoms and their relationship in space, the space-filling model would work best. This model illustrates the approximate relative sizes of the atoms in the molecule, although it doesn't explicitly show the bonds between atoms. When detail about the three-dimensional arrangement of atoms is needed, the wedge-and-dash representation is useful for sketching a molecule's structure, as it shows which atoms are above or below the plane of the paper.
Other molecular models such as the molecular formula or the structural formula provide limited information on size and spatial relationships. A molecular formula like CH4O for methanol only tells the number of atoms, without any indication of structure. A structural formula will indicate connections but not the three-dimensional layout. As for bond distances and bond angles, they provide precise spatial dimensions, measured in picometers or Angstroms, which are necessary for a deep understanding of molecular geometry.
Finally, to visualize a molecule's construction, the ball-and-stick model is helpful because it represents atoms as spheres and bonds as sticks, thus depicting the layout of the bonds between atoms within a three-dimensional space.
