Assuming the heterocyclic ring above to be planar:

Give the number of electrons that are contributed to the pi system of the heterocyclic ring by:

atom ; atom $2$ ; atom $3$ Enter NA for atom $3$ if the structure above has only two numbered atoms.

How many electrons are in the pi system of the heterocyclic ring? $($In the case of fused rings add all the pi electrons.$)$ Is the heterocyclic ring with the numbered atoms aromatic?
