In the dichromate ion, the oxidation number of chromium is+6. The sum of the oxidation numbers in Cr2O72-, a polyatomic ion, is -2, the charge of the ion. We assign -2 as the oxidation number for each oxygen, and x as the oxidation number of each chromium and write the following equation: 2x + 7(-2) = – 2…


What is the oxidation state of Cr in Cr2O7?, There are seven oxygen atoms, so the total charge is −2⋅7=−14 . So, two chromium atoms have a total oxidation number of +12 . Since one is not more electronegative than the other, we can divide the number by two to get one chromium’s oxidation number. So, a chromium atom here has an oxidation number of +6 .


Furthermore, What is the oxidation No of Cr2?, So, two chromium atoms have an oxidation number of +12. So one chromium atom will have an oxidation number of +12 /2=+6. So oxidation number of Cr in K2Cr2O7 is +6.

Finally, What is the name for Cr2O72 -?, Dichromate | Cr2O7-2 – PubChem.
