Answer:
Look at the picture.
Explanation:
So on picture two resonance structures are shown. You can see that nitrogen's electron pair is not used in aromatic system and is planar to the ring.

Answer:
In the picture attached, the Lewis structures for pyridine (C5H5N) are shown .
Explanation:
To draw this Lewis structure take into account that pyridine is a cyclic compound and it is structurally related to benzene, with one methine group replaced by a nitrogen atom (notice that with nitrogen, 2 electrons are not included in the bonds with carbon atoms). Resonance structures are drawn by analogy with benzene's resonance structures.
