It also dissolves well in solutions of chelating agents such as EDTA and oxalic acid. FeO- iron(II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Look at the chemical formula to find the charge for Iron. Tabular - Form dimensions are thin in one direction.  However, its efficacy is limited by a short diffusion length (2-4 nm) of photo-excited charge carriers and subsequent fast recombination, requiring a large overpotential to drive the reaction. { We write (III) after the element symbol for iron to show that it has a +3 charge. In chemical formula you may use: Any chemical element. As the name suggests, an empirical formula mass is the sum of the average atomic masses of all the atoms represented in an empirical formula.
