See this older answer.


A good species to practise on is the nitrate anion, #NO_3^-#, or nitric acid, #HNO_3#. Nitric acid is a NEUTRAL species; nitrate is anionic. Both species feature formal charge in their Lewis structrures. The neutral nitrogen oxides are also informative for this purpose (cf. #NO_2#).
