The oxidation state of iron in two moles or atoms of elemental iron is zero. If you mean iron (II), the oxidation state is +2.
-1 oxidation state
negative 1
Fe = +3 oxidation state Cl = -1 oxidation state
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.
0, 1 and 2 oxidation states
Oxidation: Example: two electrons removed from iron: Fe --> Fe2+ + 2e- two electrons removed from iodide: 2I- --> I2 + 2e-
In NaBrO3 the oxidation state of sodium (Na) is 1+, the oxidation state of bromine is 5+ and the oxidation state of each oxygen atom is 2-
-2 oxidation state
K = +1 oxidation state Cl = +3 oxidation state O = -2 oxidation state
Fe = +3 oxidation state Cl = -1 oxidation state
O = -2 oxidation state H = +1 oxidation state
Mg = +2 oxidation state P = +5 oxidation state O = -2 oxidation state
