It has both +3 and +2 oxidation states
The oxidation number of iron in ferrousofericoxide (Fe3O4) is a combination of Fe(II) and Fe(III) ions. The Fe(II) ions have an oxidation number of +2, while the Fe(III) ions have an oxidation number of +3. Each formula unit of Fe3O4 contains two Fe(III) ions and one Fe(II) ion, resulting in an average oxidation number of +2.67 for iron in this compound.
The oxidation numbers of iron (Fe) can vary depending on the compound it is part of. For example, in FeCl3, iron has an oxidation number of +3, while in FeCl2, its oxidation number is +2. In elemental form, such as in Fe metal, the oxidation number is 0.
the valance number of iron is 3 why,becouse in the formula after iron there is 3.the question ask you what is the valency of Fe3O4....
No. it can't be fractional. However you can get fractional answers uch as Fe in Fe3O4 where the average oxidation state is 2.666.... You need to know something about the structure that will tell you what oxidation numbers of the Fe in this case two Fe with +3 and one Fe with +2 in each formula unit.
The oxidation number of Fe in Fe2S3 is +3. This can be determined by setting up an equation where the total oxidation number of the compound is equal to zero, and solving for the unknown oxidation number of Fe.

-2 for oxygen. The oxidation number of iron depends on the oxide. +2 for Fe in FeO. +3 for Fe in Fe2O3. +2 and +3 for Fe in Fe3O4. (Note: Fe3O4 can be considered as a mixture of FeO and Fe2O3)
The oxidation number of Fe in FeBr2 is +2 because each Br has an oxidation number of -1 and the overall charge of the compound is zero.
The oxidation number of Fe in Fe3+ is +3. This is because Fe is a transition metal and can exhibit multiple oxidation states. In this case, Fe has lost three electrons to form a 3+ charge.
The oxidation number of Fe in FeO (iron oxide) is +2. Oxygen is typically assigned an oxidation number of -2, so since FeO is a neutral compound, the oxidation number of Fe must be +2 to balance out the charge of the oxygen.
The oxidation number of Fe in Fe2S3 is +3. This is because the overall charge of the Fe2S3 compound is 0, and since there are 2 Fe atoms each with an unknown oxidation number "x" and 3 S atoms each with an oxidation number of -2, the sum of the oxidation numbers must equal 0. Solving for x gives +3 for the oxidation number of Fe.
The oxidation number of Fe in Fe2O3 (iron (III) oxide) is +3. This is because oxygen usually has an oxidation number of -2, and since there are three oxygen atoms in Fe2O3, the total oxidation number contributed by oxygen is -6. This means the Fe atoms must have a combined oxidation number of +6 to balance the charge, leading to an oxidation number of +3 for each Fe atom.
The oxidation number of Fe in Fe2 is +2. Iron typically forms ions with a +2 oxidation state.
