The chemical formula that shows the relative number of atoms of each element present in a molecule is called the empirical formula.

Explanation:
Showing the simplest whole-number ratio of atoms in a compound is what the empirical formula does. It tells you how many atoms of each element appear relative to one another, not the exact number in a specific molecule. For example, glucose has molecular formula C6H12O6, but its empirical formula is CH2O, reflecting the 1:2:1 ratio of C to H to O. The molecular formula gives the actual counts in a molecule, the structural formula shows how atoms are bonded and arranged, and the term stoichiometric formula isn’t used in this context. So the description matches the empirical formula.
