C.The charges on the ions
The simplest ratio of ions in an ionic compound is called the formula unit. It represents the ratio of positive and negative ions that are present in the compound in the smallest whole number ratio possible.
In a neutral compound, the ratio of Sr2+ ions to Br- ions would be 1:2 to ensure overall charge neutrality. This means there would be one Sr2+ ion for every two Br- ions in the compound.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
The ratio of ions in an ionic compound is determined by the charges of the ions involved. The ratio is such that the total positive charge from cations balances the total negative charge from anions to maintain overall neutrality. This results in the lowest energy state for the compound.
The chemical formula of a chemical compound is established after a detailed chemical analysis.

No. The formula unit for an ionic compound denotes the ratio of ions in the compound. For example, the formula unit NaCl indicates a ratio of 1 sodium ion to 1 chloride ion, CaCl2 indicates a ratio of 1 calcium ion to 2 chloride ions, and Fe2O3 indicates a ratio of 2 iron ions to 3 oxide ions.
In a neutral compound, the ratio of Sr2+ ions to Br- ions would be 1:2 to ensure overall charge neutrality. This means there would be one Sr2+ ion for every two Br- ions in the compound.

The lowest whole number ratio of ions in an ionic compound is determined by the ratio of positive to negative ions that combine to form a neutral compound. This ratio is typically expressed in the simplest whole number form, known as the empirical formula.
1:1
C.The charges on the ions
The ratio in an ionic compound is determined by the charges of the ions involved. Ionic compounds form when positively and negatively charged ions come together in a way that balances out the charges to create a neutral compound. The ratio is then based on the charges of the ions to achieve this balanced state.
Determine the charges of the ions involved. Balance the charges to determine the ratio of ions needed in the formula. Use Roman numerals in parentheses to indicate the charge of the transition metal. Crisscross the charges to write the formula with the lowest whole number ratio of ions.
