Lewis dot arrangement for ammonia is shown by the outer electrons surrounding the N atom.
The Lewis dot structure for ammonia unveils that the N atom joins 1 pair of electrons with each of the three hydrogen atoms, resulting in a total of 3 united pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like form because of the distribution of the valence electrons according to its Lewis dot structure.
In the Lewis symbol depiction of NH3, the nitrogen atom is enveloped by three spots, each representing a pair of joined electrons
with a hydrogen atom.
