Iron ions, Fe+3, will bind to oxygen ions, O-2, in a ratio that depends on their charges since the total positive charges in the molecule must equal the total negative charges. The eventual number of positive and negative charges is found by the least common multiple of the charges.
In this instance, the charges are 3 and 2. The least common multiple is 6, so two atoms of the Fe+3 are needed to have a total positivie charge of +6, and three O-2 are needed to have a total negative charge of -6 to provide the electrical balance.
The resulting molecule is Fe2O3.
There is no such thing as Fe3O2-
However, there is a compound with the formula Fe2O3
The name of the compound is iron III oxide.
The chemical formula of iron(III) bromide is FeBr3.
You think probable to the oxide FeO.
Formula: Fe2O3
Iron (III) Oxide

This formula is Fe(OH)3.
Fe 2+
Iron fillings are pure iron - until they start rusting. So their formula is Fe.
NiCr
The Amphibole chemical formula is Mg,Fe,Ca,Na)2-3(Mg,Fe,Al)5(Si,Al)8O22OH2.
Fe is the chemical formula for iron. The Latin word for Fe is ferrum.
Fe+2 Br-1 = The ions and their chargesFe+2 Br-1 Br-1 = The ions have to add up to zero, so two -1 bromine ions cancel out one +2 iron ionFeBr2 = simplification and final answer
This chemical formula is Fe(NO3)2.
