Fluorine: -1 Chlorine: -1, +1, +3, +5, +7 Bromine: -1, +1, +3, +5, +7 Iodine: -1, +1, +3, +5, +7 The normal oxidation state of halides is -1, but with, for example, chlorine other oxidation states exist. Hypochlorites (+1), Chlorites (+3), Chlorates (+5), Perchlorates (+7). The same is true for all halogens, with the exception of fluorine, that seems to like it's -1 status and won't form fluorates.

What is the oxidation state of copper in the compound CuCl2?
+2 oxidation state for the Copper. -1 for the Chloride
Why should you not expect the halides ions to dissolve in mineral oil?
halide ions strongly interact with the counter-ions. However, mineral oil is non-polar. To dissolve the halide ions (and the counter-ions) into mineral oil would drastically raise system energy. Thus it does not work. More simply, halide ions have a charge and won't easily dissolve in non-polar substances, since like-dissolves-like.
What is the oxidation number for each element in the compound MgO?
For Mg the oxidation no is +2 while it is -2 for oxygen.
What is the oxidation number of chlorine in pbcl2?
The oxidation number of chlorine in PbCl2 is -1. This is because the overall charge of PbCl2 is 0, and since there are two chlorine atoms in the compound, each chlorine atom must have an oxidation number of -1 to balance with the +2 oxidation number of lead (Pb).
What is the oxidation number of an ion?
The oxidation number of an ion is the charge of the ion, which is determined by the number of electrons gained or lost by the atom to achieve a stable electron configuration. Positive ions have oxidation numbers that equal their charge, while negative ions have oxidation numbers that are the negative of their charge.
What are all the possible oxidation states for the halide ions?
-1 oxidation state
What is oxidation number for aluminum?
Metallic aluminium has the oxidation number zero. In compounds in the form of ions, it takes the oxidation number +III.Metallic aluminium has the oxidation number zero. In compounds in the form of ions, it takes the oxidation number +III.
What is the oxidation state of copper in the compound CuCl2?
+2 oxidation state for the Copper. -1 for the Chloride
What is the oxidation number for sulfur?
The oxidation number in atomic sulfur is 0. With other non metals, it produces many ions where its oxidation number varies from -2 to +6. The oxidation number of sulfide ion (which is produced usually with ions from metals) is -2.
Oxidation number of Cl?
Pure element has zero oxidation number. When forming ions it is equal the charge of ion.
Oxidation number of nitrogen?
Pure element has zero oxidation number. When forming ions it is equal the charge of ion.
What group has an oxidation number of zero and why?
Noble gas have 0 Oxidation number. That's because they do not form ions.
