What is the oxidation number of Cr2O72?
In Cr2O72- chromium (Cr) has an oxidation number of 6+ while oxygen has an oxidation number of 2-.
What is the oxidation number for Cr in Cr2O3?
+6 for Cr, -2 for each O in Cr2O72-oxidation number for oxygen is -2 so 7 of them makes -14 in total but the compound has an overall charge of 2- so therefore +12 is required. As there are two chromium then the oxidation number for each one is +6
What is the oxidation number of Cr in CaCrO4?
+2 for Ca, +6 for Cr, -2 for each O
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 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
What is the oxidation number of Cr2O72?
In Cr2O72- chromium (Cr) has an oxidation number of 6+ while oxygen has an oxidation number of 2-.
Why the oxidation number of Cr2O72- is 6?
It is true for chromium. But O shows 2asthe oxidation number.
What is the oxidation number for Cr in Cr2O3?
+6 for Cr, -2 for each O in Cr2O72-oxidation number for oxygen is -2 so 7 of them makes -14 in total but the compound has an overall charge of 2- so therefore +12 is required. As there are two chromium then the oxidation number for each one is +6

What is the change in the oxidation number of Cr?
Cr is a transition metal and has a variation of oxidation number from 0 in the elemental state to +6 in the dichromate ion.
What is the oxidation number of element Cr?
As with any other element, the oxidation number of Cr depends on whether and how it is chemically bonded. The oxidation number of pure elements is arbitrarily defined to be 0. In compounds, Cr has oxidation numbers of +2, +3, and +6, depending on the compound.
