Question

which of these is true for a molecular model like the one shown?
we can always identify the type of each atom based on color.
the model shows how the various atoms are connected in the molecule.
the model shows the relative sizes of the atoms to each other.
the model shows the actual size of each atom correctly.

Explanation:

• Color coding for atoms in molecular models is not universal, so we cannot always identify atoms by color.
• This type of ball-and-stick model primarily illustrates the connectivity of atoms in the molecule.
• Ball-and-stick models do not accurately show relative or actual atomic sizes; space-filling models are used for that purpose.

Answer:

The model shows how the various atoms are connected in the molecule.
