The oxidation number of
We will rewrite the formula as an equation.
The zero comes from there being no overall charge on the compound.
Each oxidation number is represented by the element's symbol.
Since this compound is not a peroxide or superoxide, the oxidation value for
Now, by putting known values in we have:
To make it clear, we must keep the positive sign even if we know it is positive.
Overall, the oxidation numbers have to equal 0 as it is an uncharted molecule.
