WebApr 9, 2024 · The oxygen atom has a 2− charge as an ion. To balance the positive and negative charges, we look to the least common multiple—6: two iron 3+ ions will give 6+, while three 2− oxygen ions will give 6−, thereby balancing the overall positive and negative charges. Thus, the formula for this ionic compound is Fe 2O 3.
WebEmpirical Formulas. An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well.
