it is +2 it is also done by causing rust
100 will be oxidation no.in Fe2O3.
The oxidation number of iron in this compound is 3. The oxidation numbers of the total oxygen atoms and the total iron atoms must be the same in a neutral compound. There are three oxygen atoms, giving a total for oxygen of 3 X 2 = 6. There are only two iron atoms; therefore, each one must have an oxidation number of 6/2 = 3.
+3 for Fe; -2 for O
O = 2-, Fe = 3+.
+3 for Fe and -2 for O.
Usually, oxygen has an oxidation of -2 (that is unless in a compound with peroxides or halogens).

100 will be oxidation no.in Fe2O3.
That compound is Iron Oxide. It contains iron and oxygens.
+3 for Fe; -2 for O
O = 2-, Fe = 3+.
+3 for Fe and -2 for O.
The oxidation number for Fe would be 3+ and for oxygen it would be 2-. This would be Fe2O3
Fe2O3. +3 for Fe, -2 of O.
Oxidation numbers in Fe2O3 are respectively: Fe => +3 and O => -2
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.
- Oxygen in almost all compounds has an oxidation # of (-2). - Your solving for the oxidation # of Fe so make this (X) - Creating an equation with what you know: There are 2 Fe in the compound, so it would be 2X. There are 3 O in the compound, so it would be (-2 * 3) = -6 2X - 6 = 0 -Do the algebra: 1) 2X = +6 2) X = +6/ 2 3) X = Fe = +3 oxidation number
