Oxygen has an oxidation state of zero (0) in HOF. F has an oxidation state of -1 and H has +1.
The most common oxidation state of -2 would be Oxygen.
Bromine is in +5 oxidation state, oxygen is -2 and sodium is +1.
S has an oxidation state of +4 in a sulfite anion as stated. In oxyanions, oxygen always has an oxidation state of -2. Therefore, three oxygen atoms will have total oxidation number of -6, requiring an oxidation number of +4 for sulfur to sum to the charge of -2 on the anion as a whole.
The oxidation state of N in HNO3 is +5. Oxygen is -2 and H is +!.
Sodium Oxide, or NaOH, has no oxidation state. It has a charge, which is zero. The elements that make up NaOH, however, do have oxidation states. The oxidation state of sodium (Na) is +1, and it will forever be +1 because it is impossible for it to be anything else, no matter what situation. The same applies for Hydrogen. Oxygen has an oxidation state of -2, and almost always will have an oxidation state of -2. There is one notable exception: H2O2. In this case, since the total charge of the compound is neutral and the oxidation state of Hydrogen must be +1 and, seeing as there are two hydrogens, bringing the overall charge up to 2, the oxidation state of oxygen must be -1. If it was -2, then the molecule would have an overall charge of -2.
oxidation state of Fluorine is always -1.
Oxygen usually has an oxidation state of -2.
Oxidation state of Oxygen in:Peroxides is -1Superoxides is - 1/2
-2 oxidation state
In compounds, magnesium has a +2 oxidation state; in most but not quite all compounds, oxygen has a -2 oxidation state. In peroxides, oxygen has a -1 oxidation state. In oxygen fluorides, oxygen has positive oxidation states.
It's simply a convention that Oxidation state of Oxygen is always -2 and Oxidation state of Hydrogen is always +1
As with any element, the oxidation state of oxygen is 0 in its elemental form.
+(1+0)/2 oxidation state
In this ion the oxidation state of sulfur is 6+ and the oxidation state of each oxygen is 2-
For the hydrogen atoms the oxidation state is 1+, for the oxygen it is 2-
In NaBrO3 the oxidation state of sodium (Na) is 1+, the oxidation state of bromine is 5+ and the oxidation state of each oxygen atom is 2-
The oxidation state of Hydrogen in the hydronium ion is 1+ and the oxidation state of oxygen is 2-
