Question

Give an example of a chemical compound that has oxidation number of an element as a fractional value

Answer 1

Answer: Fractional Values for Oxidation States

In most cases, atoms of the same element in a given compound have the same oxidation states, but each atom can have a different state than the other. For Fe3O4, two Fe atoms have an oxidation state of +3 and one of +2, which makes the total oxidation state of Fe= 8/3.
