Lewis dot structure in the case of NH3 is depicted by the outer electrons surrounding the nitrogen atom.
The Lewis point structure for NH3 reveals that the N atom shares one pair of e- with each of the three hydrogen atoms, resulting in a complete of three connected pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like shape attributed to the placement of the valence electrons according to its Lewis dot structure.
In the dot symbol representation of NH3, the N atom is enveloped by three spots, each representing a pair of connected electrons with a hydrogen atom.
