The oxidation number of an element is the "charge" the element would have if all of its bonds were completely ionic; that is, if the electron pairs of each bond were transferred to the more electronegative atom. For monatomic ions the oxidation number is simply the charge of the ion. For covalently bonded elements the oxidation number is a bookkeeping device and does not mean that the element carries an actual charge. Determine the oxidation state for each of the...

What is the oxidation number of each element in the compound below? If the oxidation number is positive, include the positive sign. For example, if the oxidation number (state) is +2, write "+2" (without the quotes). Mg3(PO4)2 is the oxidation number of Mg, is the oxidation number of P, and is the oxidation number of O.
