Answer:
The lowest whole number ratio of the elements in a compound is called <u><em>the empirical formula.</em></u>
Step-by-step explanation:
A molecular formula consists of the chemical symbols of the constituent elements of a compound followed by numerical subscripts that describe the number of atoms of each element present in the molecule.
Then, the representation of the elements that form a compound and the proportion in which they are found, or the number of atoms that form a molecule is called the chemical formula.
The empirical formula is an expression that represents the simplest proportion in which atoms that form a chemical compound are present. It is then the simplest representation of a compound. Therefore, it is called the minimum formula.
In summary, the empirical formula is a formula that indicates the simplest integer ratio of all atoms in a molecule.
Finally, <u><em>the lowest whole number ratio of the elements in a compound is called the empirical formula.</em></u>
