What is the oxidation state of nitrogen in each compound?
Here, we are going to find out the oxidation state of N atom in each of the compound.
Oxygen (O) atom belongs to Group (VIA) element in the periodic table. It has six single valence electrons. On the other hand, Oxygen atom(O) is more electronegative than Nitrogen atom(N). So, Oxygen atom can easily accept two electrons to attain a stable noble gas configuration, Thus Oxygen gains 2- oxidation state.
