Potassium is the metal here and it has an Oxidation number of +1 in every compound because all Alkali Earth metals have an Oxidation Number of +1.
(The other elements: Oxygen -2 and Chromium (Cr) +6)

+3. K is +1, O is -2 so as the total of the oxidation numbers in a neutral compound is zero Cr must be +3
0 = 2 + 6 -8
K2CrO4 potassium chromate Cr is +6
K2Cr2O7 potassium dichromate Cr is +6

What is oxidation number of K2Cr2O7?
+6 for Cr
What is the oxidation number of chromium in potassium dichromate?
potassium dichromate is K2Cr2O7. The oxidation number of Cr is -6. (Oxygen is -2, K is +1 so Cr must be -6)
What is the oxidation number of chromium in K2Cr2O7?
+6
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.
What is the oxidation number of Cr in K2Cr2O7 formula?
+6. 07 gives -14. K2 gives +2. As the molecule is neutral Cr2 must give +12. As there are 2 atoms 1 Cr must give +6.
What is oxidation number of K2Cr2O7?
+6 for Cr
What is the oxidation number of chromium in potassium dichromate?
potassium dichromate is K2Cr2O7. The oxidation number of Cr is -6. (Oxygen is -2, K is +1 so Cr must be -6)
What is the oxidation number of chromium in K2Cr2O7?
+6
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.
What is the oxidation number of Cr in K2Cr2O7 formula?
+6. 07 gives -14. K2 gives +2. As the molecule is neutral Cr2 must give +12. As there are 2 atoms 1 Cr must give +6.
What is the oxidation state of chromium in the compound K2Cr2O7?
In this kind of compound, oxygen is conventionally assigned an oxidation number of -2 and potassium an oxidation number of +1. For electrical neutrality, chromium must have an oxidation number of + 6, because 2(+1) + 2(+6) + 7(-2) is zero.
What is the oxidation number of Cr in CaCrO4?
+2 for Ca, +6 for Cr, -2 for each O
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 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 Cr2O72?
In Cr2O72- chromium (Cr) has an oxidation number of 6+ while oxygen has an oxidation number of 2-.
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.
What is the oxidation number of Cr in HCr2o7?
+6
