An oxidation number refer to the quantity of electrons that may be gained or lost by an atom. Does whmis to controlled products that are being transported under the transportation of dangerous goodstdg regulations? The fluorine atom is far to reactive to exist on its own, so naturally it bonds with other atoms in its vicinity to stabilize itself. HF: H: +1, F: -1. 7 years ago. Oxidation number of oxygen has been changed from -2 to 0. Er zijn een paar uitzonderingen op deze regel: Wanneer zuurstof in de elementaire toestand is (O 2), dan is het oxidatiegetal gelijk aan 0, wat het geval is voor alle elementaire atomen. For example, the oxidation number of Na + is +1; the oxidation number of N 3-is -3. The oxidation number of a free element is always 0. F2 ---> F(-) gains electrons so it is reduced. Fluorine in compounds has OS = −1; this extends to chlorine and bromine only when not bonded to a lighter halogen, oxygen or nitrogen. For a monatomic ion, it is the charge of that ion. EDIT: Fluorine in its gaseous form (F2) has zero oxidation state. Find out how to identify redox reactions using oxidation numbers.
