Potassium Chromate Structure – K2CrO
The chromate anion is made up of one chromium atom and four oxygen atoms.
How do you find the oxidation number of chromium?
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 .

What is the oxidation number of Fe in Fe3O4?
For Fe3O4 two Fe atoms have an oxidation state of +3 and one of +2 which makes the total oxidation state of Fe= 8/3.
What is the oxidation number of chromium in cr3+?
Explanation: +3 Oxidation number is seen in Cr+3.
Is O and O2 the same thing?
The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore we write it as O2.
Why is oxidation number of K 1?
Explanation: The metal has neither accepted nor donated electrons. The element is zerovalent. And thus in its compounds the oxidation state of potassium is almost invariably +I .
How do you find the oxidation number of K?
What is the oxidation number of chromium in cro3?
