Oxygen usually has an oxidation state of -2.
The oxidation number of oxygen in carbon suboxide is -1. In carbon suboxide, C3O2, the carbon atom has an oxidation number of +4, while the two oxygen atoms each have an oxidation number of -1 to give a total charge of zero for the molecule.
Oxidation state of Oxygen in:Peroxides is -1Superoxides is - 1/2
The oxidation state of oxygen in the compound is -2.
The oxidation state for oxygen in the oxide ion (O2-) is -2. Oxygen typically has an oxidation state of -2 in most of its compounds.
The oxidation state of oxygen in HOF (hypofluorous acid) is +1. Oxygen typically has an oxidation state of -2 in compounds, but in this case, since fluorine is more electronegative, oxygen has an oxidation state of +1 to balance the charge of the molecule.
As with any element, the oxidation state of oxygen is 0 in its elemental form.
In this ion the oxidation state of sulfur is 6+ and the oxidation state of each oxygen is 2-
The oxidation state of oxygen in the hydroxide ion (OH-) is -2.
The oxidation state of oxygen in O2PtF6 is zero. In a molecule of O2, the oxidation state of each oxygen atom is -2. Additionally, the compound PtF6 has a +6 charge, so the two oxygen atoms in O2PtF6 must have an oxidation state of zero to balance the overall charge of the compound.
Well, well, well, look who's curious about some chemistry! The oxidation state of oxygen in the OCl- compound is -1. Oxygen usually has an oxidation state of -2, but in this case, it's -1 because chlorine is more electronegative and steals some of oxygen's electrons. So, there you have it - oxygen in OCl- has an oxidation state of -1.
For the hydrogen atoms the oxidation state is 1+, for the oxygen it is 2-
The oxidation state of Mo in MoO4 is +6. This is because each oxygen atom has an oxidation state of -2, and since there are four oxygen atoms in the compound, the total oxidation state contributed by oxygen is -8. In order to balance the charge of the compound, the oxidation state of Mo must be +6.
