There is NO such compound as 'Fe2O2'.
The formula are 'Fe2O3' , and 'FeO'.
In both cases the elements of combination are iron (Fe) and oxygen(O).
The elements in Fe2O2 are iron (Fe) and oxygen (O). The compound Fe2O2 can be simplified as FeO because the subscript 2 on oxygen indicates that there are 2 oxygen atoms bonded with 1 iron atom in the formula unit.
There are 4 atoms in Fe2O2: 2 atoms of iron (Fe) and 2 atoms of oxygen (O).
The name of the compound Fe3O4 is called iron (II,III) oxide. (Wikipedia)
The elements that make up life include carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements are essential for building and sustaining living organisms.
