The oxidation number of chromium varies from +2 to +6.
Its a secret,you must study harder
0,+3,+5,+7
+6
+5 for P
+5
+5 for phosphorus and -2 for oxygen
No, Phosphorus has different oxidation states in both two ions. In Phosphides, oxidation state is -3, while oxidation state is +5 in Phosphates
zero oxidation number
+5 for P
+5
+5 for phosphorus and -2 for oxygen
No, Phosphorus has different oxidation states in both two ions. In Phosphides, oxidation state is -3, while oxidation state is +5 in Phosphates
zero oxidation number
The oxidation number of what in K3PO4? In that compound the oxidation number of oxygen is -2, the oxidation number of potassium is +1, and the oxidation number of phosphorus is +5.Realistically, in most compounds you can generally take it as a given that the oxidation number of oxygen is -2 and the oxidation number of any alkali metal is +1. In potassium phosphate, that only leaves the oxidation number of phosphorus to figure out, and since they have to come out to a total of zero ...The oxidation number of a compound is essentially a meaningless phrase.
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
In Cr2O72- chromium (Cr) has an oxidation number of 6+ while oxygen has an oxidation number of 2-.
Potassium's oxidation number is +1. Chromium's oxidation number is +6. Oxygen's oxidation number is -2.

It is true for chromium. But O shows 2asthe oxidation number.
