Lewis dot arrangement in the case of NH3 is shown by the valence electrons surrounding the N atom.
The dot point structure in the case of NH3 exhibits that the nitrogen atom shares 1 pair of e- with each of the three H atoms, resulting in a overall of a trio joined pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like form due to the arrangement of the outer electrons according to its Lewis dot structure.
In the dot symbol representation of NH3, the N atom is encircled by three spots, each representing a pair of shared electrons with a hydrogen atom.
