Lewis dot arrangement for ammonia is illustrated by the outer electrons surrounding the nitrogen atom. The dot point structure in the case of ammonia exhibits that the nitrogen atom unites 1 pair of electrons with each of the three H atoms, resulting in a total of 3 joined pairs of electrons. The NH3 molecule takes a three-sided pyramid-like structure because of the arrangement of the valence electrons according to its Electron pair dot arrangement. In the Lewis symbol depiction of ammonia, the N atom is enclosed by three spots, each representing a pair of joined electrons with a hydrogen atom.
