Explanation:
Pyridine is an aromatic compound because it follows Huckel's rule (4n + 2)$\pi$ electrons with 6π electrons within the ring.
These 6$\pi$ are responsible for conjugation over the ring by delocalization, therefore, it has a total of 6 conjugated electrons.
There is one lone pair present on N but if we consider those electrons in conjugation then total electrons would be 8 and the compound will become antiaromatic and least stable.
Hence, lone of electrons of N does not contribute in conjugation, hence not count.
