Well, without being given an equation, we presume you mean the o.n. of chromium.
H in this is +1, so H+H=+2
4 x O= -2 x 4 = -8,
therefore Cr = +6 as the whole element has to equal zero.
and i do believe in this form it normally goes to Cr +3

What is the oxidation number of Cr in CrBr?
In CrBr (chromium monobromide) Cr would have an oxidation number of +1. This compound is not known perhaps you meant CrBr3, where chromium has an oxidation number of +3

Why the oxidation number of Cr2O72- is 6?
It is true for chromium. But O shows 2asthe oxidation number.
What is the oxidation number of Fe and Cr in FeCr2O7?
The possible oxidation numbers for iron cations are +2 and +3. Oxygen in oxyanions is usually assigned an oxidation number of -2, producing a total negative charge of -14 for the seven oxygen atoms in a dichromate anion. If the iron cation has an oxidation number of +2, the two chromium atoms must have a total oxidation number of +12, which is possible when each chromium atom has an oxidation number of +6. An iron (III) cation would require the chromium atoms to have a non integral charge, which is not possible since electrons with half charges are not known. Therefore, the oxidation number of iron in the compound is +2 and the oxidation number for chromium is +6.
What is the oxidation number of the phosphorus in chromium III phosphate?
The oxidation number of chromium varies from +2 to +6.
What is the oxidation number for NH42CrO4?
The oxidation number of a compound is zero (nitrogen -3, hydrogen +1, chromium +3, oxygen -2).
What is oxidation number of chromium in Cr2O7?
The oxidation number of chromium in Cr2O7 is +7. The oxidation number of oxygen is -2, so 7 O atoms times -2 = -14. In order to balance the -14 on the oxygen atom, each chromium atom must have an oxidation number of +7, because 2 Cr atoms times +7 equals +14.
What is the oxidation number of one chromium atom in potassium dichromate?
Potassium dichroamte is K2Cr2O7, in the dichroamte ion both Cr atoms have an oxidation number of +6.
