Keeping this in view, what is the oxidation state of iron?
Iron forms compounds mainly in the oxidation states +2 (iron(II), "ferrous") and +3 (iron(III), "ferric").
Subsequently, question is, what are oxidation numbers used for? Oxidation numbers are used by chemists to keep track of electrons within a compound. We can use guidelines to assign oxidation numbers to atoms in a compound. Changes in oxidation state during a reaction tell us that there is a transfer of electrons.
Thereof, what is the oxidation state of Fe 3 O 4?
In most cases, atoms of the same element in a given compound have the same oxidation states, but each atom can have a different state than the other. For Fe3O4, two Fe atoms have an oxidation state of +3 and one of +2, which makes the total oxidation state of Fe= 8/3.
What is the oxidation number of o2?
Working out oxidation states
|element||usual oxidation state||exceptions|
|Oxygen||usually -2||except in peroxides and F2O (see below)|
|Hydrogen||usually +1||except in metal hydrides where it is -1 (see below)|
|Chlorine||usually -1||except in compounds with O or F (see below)|
