This is iron II, III oxide and features iron in both the 2+ and 3+ oxidation states.
It has both +3 and +2 oxidation states
Fe3O4 is FeO.Fe2O3 and it is always -2 for Oxygen and +2 for iron (in FeO) and +3 for iron (Fe2O3)
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....
The possible oxidation numbers for iron cations are +2 and +3. Oxygen in oxyanions is usually assigned an oxidation number of -2, producing a total negative charge of -14 for the seven oxygen atoms in a dichromate anion. If the iron cation has an oxidation number of +2, the two chromium atoms must have a total oxidation number of +12, which is possible when each chromium atom has an oxidation number of +6. An iron (III) cation would require the chromium atoms to have a non integral charge, which is not possible since electrons with half charges are not known. Therefore, the oxidation number of iron in the compound is +2 and the oxidation number for chromium is +6.
The oxidation number for iron in FeBr3 is 3+.

Never. iron shows either +2 or +3 oxidation state but in Fe3O4 its oxidation state is seems to +4 but it is actually mixture of one moles FeO and one mole Fe2O3 , (FeO.Fe2O3 = Fe3O4).
Because the other iron oxides Fe3O4, Fe2O3 would have the same name. In order for this to not happen you should indicate the oxidation number of iron.
No. Oxidation is the loss of electrons by an atom, or equivalently an increase in the oxidation number of that atom. Rust formation is one example of oxidation.
Iron II is also known as ferrous ions (Fe2+). Ferrous ions, has an oxidation number of +2. The oxidation numbers for the "odd" transition metals that have more than one oxidation number are always the number that is written after the element name (Added:) and it thereby is the charge of it ion. So Fe(III), ferric ion, is Fe3+
+3 is the oxidation no of iron(III)

The oxidation number for iron in FeBr3 is 3+.
In FeO the oxidation number of iron is 2+ and the oxidation number of oxygen is 2-.
Na2[Fe(CN)5NO]·2H2O, the oxidation number of iron is +3.
