If you have a polyatomic ion, use the Common Ion Table to find and write the formula and charge.3) Use the total charge on the non-metal (or polyatomic ion) find the charge on the transition metal.4) After the name for the metal, write its charge as a Roman Numeral in parentheses. An oxide ion is a negatively charged oxidation state of oxygen. [9] The subject is of practical importance because magnetite particles are of interest in bioscience applications such as magnetic resonance imaging (MRI), in which iron oxide magnetite nanoparticles potentially present a non-toxic alternative to the gadolinium-based contrast agents currently in use.

Open Access Lim, M. H. et al. Controlling the formation of magnetite nanoparticles presents challenges: the reactions and phase transformations necessary for the creation of the magnetite spinel structure are complex. So, iron can loose 2 electrons to leave a stable $\ce{Fe++}$ species; in your reaction those 2 electrons are gained by oxygen to give an anion that has 8 electrons in its outer shell which is a stable configuration.
