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.
The oxidation number of halide ions (F-, Cl-, Br-, I-) is -1. This is because halogens in their elemental form have an oxidation number of 0, and when they gain an electron to form an anion, their oxidation number becomes -1.
-1 is the most common. But halogens (except fluorine) will have oxidation numbers upto +7
+2 oxidation state for the Copper. -1 for the Chloride
The chlorine in PbCl2 exists as chloride ions, and the oxidation number of chloride ions is always -1.
Halide ions are typically not soluble in mineral oil because mineral oil is nonpolar and halide ions are polar in nature. Since like dissolves like, the nonpolar nature of mineral oil does not allow it to effectively dissolve polar halide ions.
It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
The oxidation number for Mg in MgO is +2, as magnesium typically forms 2+ ions. The oxidation number for O in MgO is -2, as oxygen typically forms 2- ions.

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.
The chlorine in PbCl2 exists as chloride ions, and the oxidation number of chloride ions is always -1.
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.
Pure element has zero oxidation number. When forming ions it is equal the charge of ion.
Pure element has zero oxidation number. When forming ions it is equal the charge of ion.
Noble gas have 0 Oxidation number. That's because they do not form ions.
