Which of the following best explains why a structural formula of a chemical compound is more useful than a molecular formula? a: both formulas identify the specific atoms in a particular compound. however, a structural formula also shows how the atoms in a compound are bonded together. b: both formulas identify the types of atoms in a particular compound. however, a structural formula also shows how many atoms of each type are in a compound. c: both formulas show the location of each valence electron in a particular compound. however, a structural formula also shows the ratio of protons to neutrons within a compound. d: both formulas show the ratio of protons to neutrons within a particular compound. however, a structural formula also shows the location of each valence electron in a compound.
