Which term represents the simplest whole number ratio of atoms of the elements in a compound?

• A. Empirical formula
• B. Molecular formula
• C. Structural formula
• D. Ionic formula

Answer: (A)

Verified step by step guidance

1. Understand that the question is asking for the term that describes the simplest whole number ratio of atoms of each element in a compound.
2. Recall that the empirical formula represents the simplest ratio of atoms in a compound, showing the relative number of atoms of each element in the smallest whole numbers.
3. Recognize that the molecular formula shows the actual number of atoms of each element in a molecule, which may be a multiple of the empirical formula.
4. Note that the structural formula provides information about the arrangement of atoms and bonds in a molecule, not just the ratio.
5. Identify that the ionic formula is not a standard term used to describe the ratio of atoms in a compound, but rather relates to ionic compounds and their constituent ions.
