Refer to the diagram to understand the chemical structure. Oxidation numbers are all about electronegativity difference between covalently-bonded atoms.. You can assign oxidation numbers to the atoms that are a part of a covalent compound by assuming that the more electronegative atom will take both bonding electrons.. Chemistry Explanation: oxygen has an oxidation number of -2, so -2 x 10 = -20, so since there are 4 phosphorous, each should have a +5 charge, since +5 x 4 = +20. It's not possible to produce phosphorus pentoxide by dehydrating phosphoric acid. There are 6 P--O--P bridges in the chemical structure of and .. and are complex molecules consisting of large number of Phosphorus-Oxygen-Phosphorous brigdes..
