Final answer:
The empirical formula of the compound formed between W(6⁺) and O(2⁻) is W₂O₃.
Step-by-step explanation:
The empirical formula of a compound is the simplest whole-number ratio of the atoms present. To determine the empirical formula, we need to know the charges of the ions involved. In this case, W(6⁺) has a charge of 6⁺ and O(2⁻) has a charge of 2⁻.
Since the charges need to balance out, we can determine that there would be three O(2⁻) ions for every two W(6⁺) ions. Therefore, the empirical formula of the compound formed between W(6⁺) and O(2⁻) is W₂O₃.
The empirical formula represents the simplest, most reduced ratio of the atoms present in a compound.
