'fe2o3' never heard of it !!!! Do you mean 'Fe2O3', if so
Then to find the oxidation number use oxygen as the standard at '-2'
Since there are 3 oxygens then 3 x -2 = -6 for the oxygen moiety.
This must be balanced the iron at '+6'
Since there are 2 irons then each iron atom is +6/2 = +3 (The oxidation state of the iron atom ).
NB When writing chemical formulae, single letter elements are ALWAYS a CAPITAL letter (O for oxygen , :NOT 'o'), Double letter elements are written as first letter is a capital letter and the second letter is small/lower case (Fe for iron , ; NOT 'fe'). This is the internationally recognised standard. Please see the Periodic Table on how the elements are shown.
In Fe2O3, iron (Fe) has an oxidation number of +3, and oxygen (O) has an oxidation number of -2. Iron's oxidation number is determined by balancing the overall charge of the compound based on the known oxidation number of oxygen.
The oxidation number of Fe in Fe2O3 (iron (III) oxide) is +3. This is because oxygen usually has an oxidation number of -2, and since there are three oxygen atoms in Fe2O3, the total oxidation number contributed by oxygen is -6. This means the Fe atoms must have a combined oxidation number of +6 to balance the charge, leading to an oxidation number of +3 for each Fe atom.
The oxidation number of iron in ferric oxide (Fe2O3) is +3. This is because oxygen typically has an oxidation number of -2, and since there are 3 oxygen atoms in Fe2O3, the total oxidation number from oxygen is -6. In order for the compound to be neutral, the oxidation number of iron must be +3 to balance out the -6 from the oxygen atoms.
In the compound Fe2O3, the iron atoms have an oxidation number of +3. This is because oxygen typically has an oxidation number of -2, so since there are three oxygen atoms in Fe2O3, the total negative charge from the oxygen atoms is -6. The two iron atoms must have a total charge of +6 to balance this, resulting in an oxidation number of +3 for each iron atom.
study island answer is +3 -2

study island answer is +3 -2
Usually, oxygen has an oxidation of -2 (that is unless in a compound with peroxides or halogens).
The oxidation number of Fe in Fe2O3 is +3 because oxygen typically has an oxidation number of -2 and there are 3 oxygen atoms for every 2 iron atoms in the compound, making the overall charge -6 for oxygen. To balance the charges, each iron atom must have a charge of +3.
In Iron III oxide (Fe2O3), iron has an oxidation number of +3, while oxygen has an oxidation number of -2. This allows for the overall compound to have a neutral charge.
The oxidation number of iron is +2 (Fe2+), and the oxidation number of oxygen is -2 (O2-). In iron(II) oxide (Fe2O3), which has two iron ions and three oxygen ions, the overall charge must balance to zero, so the oxidation number of iron is +3.
Oxidation numbers in Fe2O3 are respectively: Fe => +3 and O => -2
In the compound Fe2O3, iron has an oxidation number of +3 because oxygen typically has an oxidation number of -2. Iron needs two atoms of oxygen to balance its +6 oxidation state, hence the compound with the formula Fe2O3.
The formula for iron using the highest oxidation number is Fe2O3, which is iron(III) oxide. In this compound, iron is in the +3 oxidation state.
