Fluorine gas is reduced to hydrogen fluoride while water is oxidized to oxygen gas. OXIDATION STATES 4) Any atom that is uncombined and has a neutral charge has an oxidation state of 0, this is called the elemental state Example Cu(s) has an oxidation state of 0, as does Fe(s): IMPORTANT - remember if no charge is shown, assume it is 0 – not one as is algebra. The following are some rules for assigning oxidation numbers. First, find oxidation numbers of each element in the left side and right side of the equation. Usually, the change in oxidation number is associated with a gain or loss of electrons, but there are some redox reactions (e.g., covalent bonding) that do not involve electron transfer. Then, determine which atoms' oxidation numbers are changed when going to the right side. Exceptions include molecules and polyatomic ions that contain O-O bonds, such as O2, O3, H2O2, and the O22- ion. 1 Answer bubulaa Mar 5, 2017 It is a pure element.

Oxidation involves an increase in oxidation number, while reduction involves a decrease in oxidation number. They are positive and negative numbers used for balancing the redox reaction. Oxidation number is 0 because F2 is a diatomic molecule. Explanation: When the element is pure, it means that it is not mixed with any other elements. Similarly fluorine would consequently have an oxidation number of -1 since $$6x + 6 = 0 \Rightarrow x = -1$$ (the right-hand side is equal to zero since that happens to be the net charge on the overall chemical formula). 3. You could eventually get back to the element vanadium which would have an oxidation state of zero. Fluorine in its natural, elemental state consists of a diatomic molecule. hence, it is a redox reaction and more specifically , it is a disproportionation redox reaction.
