classical method and stock method
In the compound Co2O3 cobalt has an oxidation number of 3 while oxygen has an oxidation number is -2.
Cobalt has an oxidation number of 3 (III) in the compound Co2O3.
Xe when it is not in a compound has an oxidation number of 0
Xe when it is not in a compound has an oxidation number of 0
Usually, oxygen has an oxidation of -2 (that is unless in a compound with peroxides or halogens).
transition metals have variable oxidation states
+2 oxidation state for the Copper. -1 for the Chloride
This compound is sodium thiosulphate. S represents +6 oxidation number.
This is a neutral compound. Oxidation number of it is +2.
The oxidation number of lead (Pb) in the compound PbCl2 has to be what?
0 because all compounds have an oxidation number of 0. It's the ions (fe S O) that have oxidation numbers, The sum of these oxidation numbers always = 0 in a compound and hence a compound has a oxidation number of 0. :-) hope this helped....
