answered
In Cr2 (chromium(II)), chromium has a +2 oxidation state, which means it has lost two electrons and is behaving like a metal. Metallic behavior is characterized by elements or compounds that readily lose electrons to form positive ions.
In CrF6 (chromium(VI) fluoride), chromium has a +6 oxidation state, which means it has gained six electrons and is behaving like a non-metal. Non-metallic behavior is characterized by elements or compounds that tend to gain electrons to form negative ions.
Therefore, in terms of non-metallic behavior, Cr exhibits greater non-metallic behavior in CrF6 compared to Cr2.

To determine which compound, Cr2 or CrF6, exhibits greater non-metallic behavior for chromium (Cr), we need to consider the electronegativity difference between chromium and the other elements in each compound.
In Cr2, chromium is bonded to another chromium atom. Since chromium is a transition metal, it tends to exhibit metallic behavior. Transition metals generally have low electronegativity values and tend to lose electrons to form positive ions.
On the other hand, in CrF6, chromium is bonded to six fluorine atoms. Fluorine is a highly electronegative non-metal. When a transition metal like chromium is bonded to a highly electronegative non-metal, it is more likely to exhibit non-metallic behavior due to the stronger attraction of electrons towards the non-metal.
Hence, in CrF6, chromium exhibits greater non-metallic behavior compared to Cr2.
