Oxygen almost always has an oxidation number of -2, except in peroxides (H 2 O 2 ) where it is -1 and in compounds with fluorine (OF 2 … That's because fluorine is more electronegative than oxygen, and F is assigned an oxidation number of -1. Fluorine (F) ALWAYS has an -1 oxidation number, since it is so electronegative. (O in NO is -2) The oxidation number of Fluorine in a compound is always-1. In oxygen difluoride (OF2), the oxidation number of oxygen is +2, while in dioxygen difluoride (O2F2), oxygen is assigned an oxidation number of +1 because fluorine is the more electronegative element in these compounds, so it is assigned an oxidation number of -1. -1 Rule 7: The oxidation number of fluorine is always –1. Physics. 6. When iodine forms a compound with a high electronegative atom it's ON becomes positive. If you ever come across an equation involving OF2, you can use either set of values for the oxidation numbers, make electrons lost equal electrons gained, and you will get the equation tobalance.
