∙ 12y agoOxygen's oxidation number is minus 2 or (-2), the state it has in most of its compounds.
In a neutral compound, the sum of the oxidation states must be 0. The two iron atoms give 2 x 3 = 6, therefore the three oxygens must give 3 x -2 = -6 to balance it out.

In the compound Ni2O3 nickels oxidation number is and oxygens oxidation number is -2?
- 2 for each O, +3 for each Ni
What is the oxidation number of Ca(NO3)2?
The sum of the oxidation numbers is zero for the compound.
In the compound Fe2O3 irons oxidation number is while oxygens oxidation number is 2?
The oxidation number of iron in this compound is 3. The oxidation numbers of the total oxygen atoms and the total iron atoms must be the same in a neutral compound. There are three oxygen atoms, giving a total for oxygen of 3 X 2 = 6. There are only two iron atoms; therefore, each one must have an oxidation number of 6/2 = 3.
What is the oxidation number of O3?
THe oxidation number for 'O3' is zero(0). O3 is ozone, and each oxygen atoms forms two single bonds with each of the other oxygens, forming a triangular arrangement.
In the compound Co2O3 cobalt has an oxidation number of what?

In the compound Al2O3 aluminum has an oxidation number of 3 while oxygen's oxidation number is .?
In the compound Al2O3, aluminium has an oxidation number of +3, while oxygen's oxidation number is __-2 ____. For aluminium oxide (Al2O3) to form the ionic charges MUST balance. Hence For the 2 aluminiums it is 2 x 3 = +6 For the 3 oxygens it is 3 X -2 = -6 +6 -6 = 0 So the charges balance, hence Al2O3 is neutrally charged compound and NOT an ion.

What is the oxidation number of sulfur in Na2S2O8?
+6 for each sulphur. +1 for each Na; Two oxygens are as peroxides and will have -1 charge / oxidation number each. Six oxygens are as oxides and will have -2 charge each. So, 2(+1) + 2y + 2(-1) + 6(-2) = 0 Or y = +6 (the charge / oxidation number of sulphur)
