The rules because that assigning oxidation numbers room in the Chemist"s tools

and follow the eleven rule to entrust oxidation number to atoms in a chemistry formula.

Let"s go with the examples listed below to see how it"s done.

now let"s take it a look at sodium nitrate, NaNO3. What is the oxidation number of nitrogen?

First that all, let"s mental what we"ve learnt:

To determine the oxidation variety of nitrogen, we apply

Rule #6: Oxygen is commonly assigned one oxidation variety of -2 because that oxides. In this case, we have three oxygen atoms in NO3-.
ascendancy #9: The sum of oxidation numbers of one ion or complicated ion is the very same as the fee on the ion.

Let the oxidation variety of nitrogen be stood for as N. Set up the equation and also solve for N.




You are watching: The oxidation number of n in nano3 is

N + 3 (-2) = -1
N = +5

The apparent charge ~ above nitrogen is +5.
