Jun 23, 2021· Fractional oxidation states are allowed because oxidation states are a somewhat arbitrary way of keeping track of electrons. In fact, Fe 3 O 4 can be viewed as having two Fe 3 ions and one Fe 2 ion per formula unit, giving a net positive charge of 8 per formula unit. Fe 3 O 4 is a magnetic iron ore commonly called magnetite. In ancient times, magnetite was known as lodestone because it
