'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 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.
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.
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.
Fe2O3 +3 for each Fe -2 for each O
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.
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.
Oxidation numbers in Fe2O3 are respectively: Fe => +3 and O => -2
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.
