Valency is the number of electrons in the valence shell. Oxidation state is the formal charge on an atom/ion.

∙ 13y agoiron is in the III oxidation state
The oxidation state of Fe in FeBr2 is +2. The oxidation state of Fe in FeBr3 is +3.
The highest oxidation state for an element is +7, but this is not unique to any one element: All of the halogen elements except fluorine have oxyacids with this oxidation state.
Cupric is used when copper is in a +2 oxidation state while cuprous is used when copper is in a +1 oxidation state.
Tungsten metal doesn't have any charge. In its compounds, tungsten can have different oxidation states / charges. The most common formal oxidation state of tungsten is +6, but it exhibits all oxidation states from −2 to +6.
Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
State of Hg in Hg2Cl2 is 1
Two (2), oxidation state is -2 .
Overall the valency is 2.5. 2 of the S atoms have a valency of 2 and 2 of the S atoms have a valency of 3.

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....
Because they have only one electron in their valency shell. The second oxidation state would require the atom to lose an electron from its penultimate shell which is full.
It depends on what form it is in. It can be in the 4+ oxidation state, 4- oxidation state and every oxidation state in between.
