What is the oxidation number of nitrogen in NaNO3?

David Southern  Follow

Oxidation number of N in NaNO3 is +5.

O N of Na is +1 and that of O is -2. Suppose, O N of N is x.

So, +1 + x + 3*(-2) = 0

x = +5

Hope this helps.

Without doing your homework, I will provide a hint.

Na is +1

O is -2

There are 3 oxygen.

Since this is a stable element the resultant charge is 0. So the + and - must balance.
